1. Funnel fill heavy latex party balloon with two bottles of Liquid Ass fart spray.
2. Pressurize with water till it fits snug in an old Amazon box.
3. Add double sided tape to inside box flaps, so balloon surface sticks to the lid when closed (this should ensure detonation even if the thief is careful when cutting the tape)
4. Seal with packing tape. For added effect put a "Fragile: Electronics" sticker on it.
I left this bouncing baby shit bomb on my porch this morning, went riding all day, came home and.......GONE. I'm just picturing the son of a bitch opening this in his living room or in his car and I can't stop smiling. Your move, scumbag.
