Once, as an April Fool's joke, I called a friend and told her I was at a really fun party. She wrote down the address and zoomed on over.
I wasn't there.
Not only had I sent her to a guy's house who wasn't hosting any sort of soiree, he was actually heading out on a date.
While it's not my proudest life moment, my friend was a fantastic sport and we laughed about it for a long time.
What's the biggest April Fool's joke you've ever pulled or were pranked with?
