Here's are some of the oldest (and dumbest) April Fool's Day pranks. Perform them at your own risk:

  1. Glue a quarter on the floor.
     
  2. Tie someone's shoelaces together.
     
  3. Turn on and crank up someone's car radio, wipers, and heat.
     
  4. Set all clocks an hour ahead.
     
  5. Put a rubber band on the sink sprayer.
     
  6. Replace Oreo filling with toothpaste. Or use toothpaste as a frosting for cupcakes.
     
  7. Remove the labels on all the canned goods in the house.
     
  8. Make some pinholes in a plastic cup.
     
  9. Sew the legs of someone's jeans shut.
     
  10. Dog doo, a paper bag ... and matches.
