I tried this Opener out last night and got some really good responses. Let me know what you think.
"Hey guys, I've just come up with the best punchline ever, but I need help writing the joke. I'm trying to get to a point where I can say "Cock" and "Asian" but say it as "Caucasian." Any ideas?"
Exactly how I presented it, I got a ton of laughs right away. What's fun, though, is the more you use this, the more ideas you'll actually have for a joke, and you can throw them out in later sets, saying "Well, I did think of this..." etc.
Let me know what you think.
