I convinced my sister for years that the tamarinds (fruit) in worcestershire sauce were actually tamarins (monkeys), which, as she was a precocious vegetarian, prevented her from eating it.
A childhood belief about general

others believed things like this
- My sister thought a fruit machine (the gaming device) could turn one item of fruit into another.— Richard Davies
- My Dad told me that Soy Sauce was made of grasshopper spit! I didn't eat it for YEARS!— TawnyKat
- My father used to call soya sauce "monkey blood". I didn't even consider tasting it for years!— Me
- I used to think that Tabasco Sauce contained tobacco, and therefore was actually "tobacco sauce."
Anon - When I was 4, I thought that if I ate Fruit Gushers, my head would turn into a fruit. — Joe
- I used to believe if you ate a seed from a fruit, a tree of that fruit would grow inside you — kels
