Here is my secret list to annoy your friends and enemies. This is centuries old so use with care.
#1. Walk up to random people and ask what gender they are.
#2. Ask the waitress at a resturant for an extra seat for your imaginary friend.
#3. Sing your own theme song while riding in an elevator full of people.
#4. When pulled over by a cop say: "I thought you had to be in relatively good physical shape to be a police officer."
#5. When at the pool, point and laugh at fat people in swimsuits.
#6. Ask Jewish People if they liked "The Passion".
#7. While sitting in a bathroom stall, ask the person in the stall next to you for toilet paper.
