Tickle Quiz
..
Better if your victim is more intelligent than average. Tell him if he can answer the next question, you'll untie him and let him go.
Me: What's the capital of North Dakota?
Him: Bismarck
Me: Sorry, wrong answer.
Proceed to tickle him for five minutes despite his laughing protests and shouts of "unfair!". After the five minutes are up, realize he was right, look sincerely apologetic, and say you'll take the punishment back. Tickle him for five more minutes, except in reverse.
