Years ago I got a bag of doughnuts and injected them with mushed up tofu. Then I told my nephews they were Boston Cream doughnuts and gave them the bag. Their mother was always trying to get them to eat healthy and they fucking hated it so they figured their uncle had really come through for them.

They scarfed them down like only pubescent boys can, never pausing for long enough to notice that the cream wasn't very creamy. Then I told them the truth and laffed my ass off. Oh man if looks could kill I'd have been a dead man that day.

They swore they'd get even. To this day I still watch my ass when we go to visit.
