I should probably do work today so someone suggested this a little while ago, and I'm sorry to whomever did because I can't remember who you are. The game is you type the punchline to your favorite joke. That's it. Then we all try to guess the joke.
When I was younger I always got stymied, so maybe someone here can help, by this one commercial. It was for some cereal and it apparently gave the kid confidence enough to run with the punchline, "And I said, that is my foot!" I could never come up with a joke that would be remotely funny with that punchline. Bonus to whoever remembers what the commercial was for.
