the time i had to go so bad in college i went poo poo in my girlfriends cat's litter box while she was in the shower and told her that her beloved cat was sick and we needed to take it to the vet ASAP. 8)
You told me that one. I laughed so hard then and I'm laughing right now but that's really disgusting!
Did I ever tell you about the time I pulled a prank on my son? When he was sleeping I put little freckles all over his face with eyeliner. Funny thing was he was late for work so he ran out of the house with it on! LOL I got a scathing call later but I was laughing so hard I couldn't take it seriously. After all a prank is just a prank.
The time I painted my husbands toe nails when he was asleep and then realized I didn't have any nail polish remover.
