- Glue the headset of someone’s phone down to the cradle.
- Put plastic wrap around the door frame of a commonly used door.
- Cover a toilet seat with plastic wrap.
- Leave a note on someone’s car apologizing for an accident that never actually happened.
- Glue all the eggs into the carton.
- Hard boil all the eggs in the carton and place them back in the refrigerator.
- Paint a bar of soap completely with clear nail polish so it won’t suds up.
- Turn every setting in someone’s car to the maximum: the heat, the radio, the wipers, the seats, etc.

- Conference call two people then don’t say anything, just listen.
- Place a ‘house for sale’ ad in the newspaper for someone’s home.

- Rubber band the sprayer on the kitchen sink into the “on” position.
- Hide an alarm clock in someone’s bedroom and set it for 3:00 a.m.
- Remove the shower head and place a chicken bouillon cube in it, then put the head back on.
- Rearrange somebody’s drawers or file cabinets in a different order.
- Cup some water in your hand and pretend to sneeze on the back of someone’s head.
- Tape magnets to the bottom of a cup, put it on the roof of your car and drive around.
