When I was like 12 or 13 I got this toy eyeball that would always look up however you moved it or rolled it across the floor. One night I was getting something from the fridge and saw a box of some kind of Entenmann’s cake in there and had a fantastic idea. There was a little part of the box where you couldn’t see through the cellophane and it was just big enough to hide that eyeball toy and no one would ever see it until they opened the box. Of course I went ahead and put it in there and then went back to watching TV. A few hours later my older sister got home, and apparently had been thinking about that Entenmann’s cake all day at work. I summoned every ounce of willpower to keep a straight face when I saw her go into the kitchen, then I waited… A few seconds later there was a bloodcurdling scream that brought everyone in the house running to see what was going on. My sister came out of the kitchen to find me doubled over with laughter on the sofa. I forget exactly which explitives she shouted at me, but the next thing I saw was that eyeball whizzing past my head at about 90mph, leaving a small dent in the wall behind me lol

I’m 42 now and she’s 50 and it still gets brought up from time to time lol
