My dad usually got me and my sisters pretty good. I was away at college when my parents finally got a dog. I had just got back from putting a new tire on my dirt bike during spring break and Dad convinced me the dog chewed the new tire. He's convinced my sister that her (fixed) cat had kittens. Best/worst one was my sister getting my dad back by convincing him that my grandparents in their dementia had accidentally caught their inlaw apartment and our house on fire by leaving candles burning.
Last year I removed the filling in oreos and replaced it with toothpaste. Left it on the break table at work and got cussed at all day. This year I am off but left a pack of unadulterated cookies on the table and am curious if anyone will dare try them or if they are still traumatized from last year.
I din't prank anyone but my 12-yo son did. He put a bowl of sugar on top of the refrigerator, balanced on the door, so my daughter got a head full of it when she opened the door. He mixed up shaving cream and food coloring and cat food and spread it on the basement floor so it looked like the cat had a major accident. He also put drops of blue food color in a brand-new bag of burger rolls so it looked like the rolls were moldy. He said there were a couple others but I haven't found them yet. I'm gonna get him back.
