while he's asleep.? What's the best practical joke, like putting water on someone's hand while he's asleep. or putting foam on someone's hand and tickling his nose. Anyone?
stuffing a fake snake up into the toilet, first tying kite string or fishing line around it's head then placing the other end of the string outside the bathroom. as soon as you know someone is on the toilet pull the snake out just hard enough that it touches their butt, then they look to see what it is, and I can almost guarantee U they come out of the bathroom with their pants down and screaming.
