To test my idea, I went onstage and began: "I'd like to open up with sort of a 'funny comedy bit.' This has really been a big one for me...it's the one that put me where I am today. I'm sure most of you will recognize the title when I mention it; it's the "Nose on Microphone" routine [pause for imagined applause]. And it's always funny, no matter how many times you see it."

I leaned in and placed my nose on the mike for a few long seconds. Then I stopped and took several bows, saying, "Thank you very much." "That's it?" they thought. Yes, that was it. The laugh came not then, but only after they realized I had already moved on to the next bit.

Now that I had assigned myself to an act without jokes, I gave myself a rule. Never let them know I was bombing: this is funny, you just haven't gotten it yet. If I wasn't offering punch lines, I'd never be standing there with egg on my face. It was essential that I never show doubt about what I was doing.

Thanks Lexica, i've always enjoyed Steve Martin, but never read up on him or anything. Have you seen the newest Pink Panther? He's good in that one.
