Jamestown Jellyfish

Having a roommate sucks, and thus the Jamestown Jellyfish is a pleasurable way to leave a vengeful treat for your unsuspecting roommate. All you need is a shower and your hand. When your roommate won't leave the house, but you have the desire to rub one out, get in the shower, jerk off, and blow a load in the floor of the shower. Immediately shut off the water so the jellyfish does not disappear down the drain. The next time your roommate goes to take a shower he/she will find your special marmalade lurking in the tub.

Dude, I need to jerk off and my roommate won't leave, so I went into the shower and left a Jamestown Jellyfish for him on the shower floor. He stepped in my gelatin the next day--that will fix his wagon!
