For example, when I was ~5 or so, my mom told me that the chicken skin on KFC chicken was bad for my heart. I thought I would literally drop dead on the spot if I ate too much of that, and semi-freaked out because I ate a small piece.
Example 2: To remember where the utensils went when setting the table, I labeled the spoon as the damsel in distress being held hostage by the knife villain and the fork knight had to get through the plate castle to rescue her. Idek.
What are some silly/funny things you thought as a kid?
