1. Step off a curb with your eyes shut. Imagine it’s a cliff. To get any benefit out of this one, you have to have a good imagination. Don’t step off immediately, build up to the jump. Study the ravine below. Feel the winds at that altitude. Step off and …AHHHHHH!!!!!!!
2. Stare at the back of someone’s head until they turn around. This works on the ” I have the feeling I’m being watched” principle.
3. Pour water in hand, make sneeze noise, throw water on back of another person’s neck. This is always a good gag. For an even bigger reaction, act like you’re not sorry at all for what they think you did. Comment instead on how big that sneeze was or about how there was a lot of mucus in that one.
