What was the greatest length you went to just to fuck with someone?

I'm too late to the party for anyone to see this but whatever.

In 1999 I was hanging out with a few friends one night and we decided to get pizza. We're at a house in the middle of nowhere about 40 minutes from the closest pizza place so someone has to go pick it up since delivery is not an option. My friend and I rock paper scissors for it and he loses. I give him some money and ask him to rent a movie at Blockbuster (it's 1999) while he's in town. He leaves.

I immediately decide to fuck with him. We both drive 1993 Dodge Spirits and my key works for his car perfectly (I could also open another friend's Dodge Caravan). I tail him 30 miles to the pizza place and watch him go in to get the pizza and come out then follow him to blockbuster. When he goes in to get the movie I steal the pizzas out of his car and then drive all the way back to the house laughing the entire way. I put the pizzas in the oven to hide them and wait for him. This is before we had cell phones so he can't call and I know for a fact he doesn't have any extra money. About 20 minutes later he comes in the door and he has this worried look. I ask him where the pizzas are and he starts frantically explaining that they were stolen and he knows it sounds crazy but he locked the car and he's sooooo sorry and he promises he really did buy them and didn't steal the money and he can't believe it blah blah blah I let him go on for like 5 minutes frantically apologizing. He was actually still going when I walked into the kitchen, grabbed the pizzas and just walked out and handed them to him. The look on his face was a complete WTF. He literally could not process what was happening or how I got pizzas or that they were the same pizzas. It took him like 30 seconds to realize what was going on and for the next 20 minutes he yelled "god damnit!" at random intervals.
