A childhood belief about eating

others believed things like this
- To clean the goldfish you put washing up liquid into its bowl.— Sev
- I used to believe that the reflection at the bottom of cup of liquid was a crocodile waiting to gobble me up.— Aaron
- I used to believe that arson was a flammable liquid, not the act of deliberately setting fires.— Joey Schwartzman
- I used to believe the Golden Calf produced liquid gold instead of milk.— Trisha
- I always believed as a child your stomach was a big hand which squeezed your food out through your bum....— amc
- We put food in our mouths, so naturally I believed my stomach was in my head.— Timb
