What's the funniest prank ever played on you?

My best friend and I stayed up till 1am after her dad went to work and went out and moved her moms brand new car around to the back of the house so when she woke up the Weiter morning to go to work she thought someone had stolen her car (she was famous for leaving her keys in the car), so that morning we woke up to her freaking out on the phone with her husband saying someone stahl, stola my car its gone, and its a good thing we went upstairs when we did because she was getting ready to call the cops. We just stood there laughing when she is telling us she was on the verge of tears and we sagte go look out the back window and she was like Du little witches lol, she should have known it was april fools Tag lol.
