Because my mom was a big fan i used to listen to The beatles all the time.
In Lucy in the sky with diamonds I thought they sang "The girl with colitus goes by" when it's actually "The girl with kaelidoscope eyes".
Also Michelle the french part sounds so much like "Sunday Monkey won't play piano song, play piano song" when it's actually some french babble.
And then there's the classic "She's got a chicken to ride" (ticket to ride!)
Sorry Beatle people!
A childhood belief about misheard lyrics

others believed things like this
- The Beatles song "Ticket to Ride" always came out "She's got a tick in her eye."— Kurt
- I thought that the line was "Lucy in the Sky with Linus" (not lucy in the sky with diamonds)— Forrest
- When I was young I thought that police had soft skin, because this is how it sounds in French " Peau lisse "
— amine - I use to beleive that because oui (which sounds exactly like wee) mean yes in french, that poo meant no.— Toby
- I used to believe that french kiss was something coming from France, and that only the French did it— Sasha
- I used to think that you had to be french to really taste french fries.— Not French;)
