Lay out lots of paper on the floor. Place several raw eggs around on the paper. Choose a victim and tell them to memorize where the eggs are. Tell them to wear their shoes and blindfold them. While you are blindfolding them, have someone else who is in on the prank remove the eggs and replace them with small stacks of crackers, not necessarily in the same place. Let the victim begin walking across the paper. They will be trying to avoid the eggs and will be stepping on crackers. Make appropriate comments, like “Ewww….” Make sure the person you choose as your victim is able to take a joke.
