Ha!! As an appliance repair guy i learned about reversing the door hinges+handles a long time ago. It never occurred to me to use it for a prank until i was living in my apartment for a few years, and realized it really would make more sense to reverse the hinges to open the door the other way. I moved the hinges, but then it occurred to me that i can leave the handles where they were and prank all my friends when they came over. Unsurprisingly, it works! People usually would figure it out eventually but sometimes we had to intervene if they were getting too rough with it.

I got so used to having it set up that way that once in a blue moon I'd go to open other people's refrigerators the wrong way (not the best look for a repair tech, LOL)
