Here is a Terrance & Philip word game to play:
Me: "Want to play a game, Buddy?"
You: "I'm not your Buddy, Friend!"
Me: "I'm not your Friend, Guy!"
You: "I'm not your Guy, Dude!"
Me: "I'm not your Dude, Fella!
Repeat until Hesitation, Deviation or Repetition occurs. The last word must be previously unused, loosely equivalent to "Buddy" or "Guy", and delivered quickly.
Co-op version: Set a timer for 2 minutes and see if you can keep it up.
3 player version: If you said "I'm" last time, you must say "He's" this time, and vice versa.
