How I did it: I had played a game at lunch (in highschool) where everyone present set their music players to shuffle and made a "life's soundtrack" to the randomness. When it came my turn, my greatest fear apparently involved "applebottom jeans and boots with the fur." I wasn't quite sure what happened next, then I belatedly realized my boyfriend had milk coming out of his nose. It put me off my lunch, but certainly made the day interesting.
Lessons & tips: Be a very random, spontaneous joker. Catching someone offguard with a joke or quip can easily cause this.
Resources: Too much free time, and easily amused friends.
