When I was younger my brother told me he had to tell me a very sad secret. The secret was that when I was thirteen, my head was going to explode. There was no way I could tell my parents, because it was too sad of a subject for them and would really upset them.
I eventually forgot, until couple years later, a kid in class told us that he had a friend whose head blew up...
Turns out they were both lying! Luckily for me, I still have my head.

When I was about 6, I had my little sister (age 3) convinced that a picture of a girl sitting in a field with a barn in the background was me before she was born and that we lived on that farm. I had her going for a few years before she realized it wasn't true.

When I was little, my dad told me that fish lived inside of my waterbed. I still remember trying so hard to see through the rubber lining so I could see the fish.

We were told that if you lied, your tongue would turn black. My parents would make us stick out our tongues when they thought we were lying and say, "Yes, your tongue is black." We'd run for the mirror...but they told us that only grown ups were able to see the black.

When I was 5, my 10 year old sister told me that our family was once so poor, we had to live in a matchbox. I believed her!

Kate

I used to believe that if I told a lie my tongue would turn purple and so that way if my Mum thought I was lying she'd tell me to stick out my tongue and could always tell if I was lying or not by how quickly I stuck it out. God I was stupid...

My brother once convinced me to drink a puddle of mud by putting a straw in it and saying it was a chocolate milkshake.

...He also filled a bottle with warm soapy water and threw it all over me and told me it was acid. I cried.

When I was very young my parents used to tell me I was found under a rock. Naturally, after being told this for years I believed it.
All was fun and games till we were at a grocery store when I was eight and an old friend of my mom's asked where I came from.

my friend at camp told me that he used to live next door to the 20th century fox logo because the rent was cheap,but getting some sleep was next to impossible because of all the fanfair music and lights, he said that his father used to
shout out the window at it and say; Hey!! give it a rest allready! I'm trying to sleep!!

when i was a little girl, i noticed that my mother had a tattoo. when i asked her how she got it, she told me that it appeared on her ankle (thats where the tattoo is) after she had eaten several breath mints. (you know the ones with the little red and white swirls) so obviously, i thought that this was true so i persuaded her to buy me an entire bag of them. i finished that bag 45 minutes later. imagine my disappointment when my tattoo didn't appear! i cried for about 3 days. ;) but lucky me, i got the press on tattoos. (the ones that rub off with soap and water) hehehehehe ^_^

When I was around six or seven, I asked my father what air was made of. He told me, straight-faced, that it was made of whipped egg whites and raisins.

Around same time, my brother asked what owls were made of, to which he answers 'popcorn and juice'

I never really got his sense of humor back then...

We used to have a bunch old skeleton keys, they were on a big ring, and the keys were huge, and the hung on a old wood burning stove/fireplace in our house. I would play with them a lot. One day I was about 5 I asked my dad what they were for, and he told me that if I was ever bad, he would show me.. He said that the police asked him to take care of the really bad criminals and monsters and that they lived in a jail in our attic, and that those were the keys to the cells. He said their favorite thing to eat was bad little kids, and that they must be starving by now because he hadn't fed them in a while... I was scared to death! When ever my cousins or friends would come over and start getting loud I'd warn them about the attic, and the keys. I believed that for a very long time.

When i was younger my grandma told me that the nuts that was on the bread were bug wings, i still ate it.

When I was little my mum used to tell me that my eyes would turn green when I lied so I would stand in front of the mirror and say things like, "I am 100 years old" or "I am a boy".

My mum said it only worked for proper lies like, "It wasn't me" and "I didn't do it" and only mothers had the power to see this transformation

Rose

My brother actually believed this. One day, we watched Pinochio, and my mom told him that when he lied, his nose would grow, just like Pinochio's... well, whenever he would say something, like "I'm hungry", or, "Lisa called me a name and hit me", he would touch his nose to make sure it wasn't growning... and still to this day, every once in a while, he taps his nose when he is talking...haha. He is almost 13 now...

Lisa

I have known my best friend for about 20 years but when we first met I couldn't stand her. I thought I was quite a clever child and I knew that 'twins' meant 'identical' so I was always angry with my friend because she used to say she and he brother were twins and I knew that was a lie because she was a girl and he was a boy. I couldn't understand why she lied so much or how she thought anyone would believe her!

My dad was in the Navy when I was small so I grew to love all things naval. We would watch all of the war films, especially the naval ones. There was one film which showed the men in the torpedo room wearing white masks on their faces whilst loading the torpedoes. "Why do they wear those masks, dad?" I asked. He replied, "That's only the men with false teeth - it's so they don't fall into the tube and jam the torpedoes." This is another one I truly believed and even relayed this knowledge to others!

We were watching a house fire on the news and I was about 4 or 5 and my older sister who would have been 7 or 8 told me that everyone's house would burn down at some point in their life. She also told me the same thing about accidentally stapling your finger like she did one day. I was terrified of the day that I'd have to feel that pain.

When I was younger my Mom told me and my older sister that if we lied she could see the devil in our eyes. Whenever we'd lie we would check each others eyes to make sure he wasn't in there.

When I was three or so, my mother worked for a local radio station. She took me into work one day and I was playing with one of those wall-mounted, rotary pencil sharpeners. All I was doing was spinning the lever around. I must have been making an obnoxious noise, because one of the women who worked there came by and told me, "If you keep on doing that, McDonalds will explode."
I believed this up until my first day of kindergarten, when someone used the sharpener, I broke down crying, and made my mom take me to McDonalds after school to make sure that it was still there.

The kicker is that I didn't like McDonalds, even then.
