A great prank/fun thing to do where the loser (or random selected persona) has to stand 5-10 feet away from a group of people usually consisting of at least 4 people. The group of people use water guns filled with ice cream sundae toppings (like caramel, chocolate sauce, cherries, sprinkles, marshmallow fluff, whipped cream, and nuts) and spray away at the poor sucker, who will be humiliated at the mere fact that they are now a living ice cream sundae. For maximum fun, do this in a public place, i.e. a park or a random sidewalk.
