Here's the first one
Leave 'Em Hanging
Quick and easy classic prank. Just wait until your victim is in the shower, then sneak in and grab their clothes and all the towels. (You might want to get the bath mat too!)
Step 1: Salty Surprise
Simple: put salt on the victim's toothbrush. Then stand by to watch the surprised look on their face.
Step 2: Avalanche
For this prank, the victim's bedroom door must open to the inside, and they need to be a sound sleeper. While the victim is inside the room, quietly tape newspaper across the door jam, covering it almost to the top. Then fill the gap between the newspaper and the door with Styrofoam peanuts, popped popcorn, crumpled newspaper, or even water balloons. When the victim opens the door, they'll be greeted by an avalanche.
Step 3: Rude Awakening
Sneak up on your victim while they are sleeping and put some shaving cream in their hand. Then tickle them on the nose with a feather and watch while they give themselves a face full of foam!
Step 4: All Sewed Up
Sew someone's coat cuffs together so they can't get their hands through. Or go through their underwear drawer and sew the legs of all their underwear closed (if you use a sewing machine, this doesn't take too long!).
Step 5: Sudden Shower
Turn the showerhead so it will spray the victim when they stand outside the shower and turn on the water.
