What are good pranks when people are asleep?

While someone is sleeping, CAREFULLY put their fingers or hands into lukewarm water. In the morning or whenever, you and that person will find out that they have wet the bed! Great for sleepovers! It is because everyone will think that person is a bed wetter!

Another is to fill their hand with whipped cream and scratch their nose! They will smack their face with the cream instantly! Experiement and enjoy.

Another would be to paint a guy's toes glow in the dark!

Lastly, try writing "loser" backwards on their head, so that when they look in the mirror, they can read it!
