When you take a pause before delivering your punch line, you will be using silence as a creative entity in itself.

You can't wait forever for an audience to get the joke, but you should give them at least two seconds to join in before you go on to the next one.

It's better to play to the host as though in a real conversation and let the audience listen in- which they are.

Don't try to give a funny opinion; give your opinion in a way that will be funny.

In addition to listening to the audience's laugh, you want to listen to their silence. Is it bored or interested silence? The silence is quieter and filled with energy when they're interested. You can hear a pin drop. When they're bored, you can always hear it.

Walking back and forth also helps by creating the illusion that you are thinking of the routines on the spot, giving your performance a more spontaneous feeling.

This whole urban rap thing needs to be pulled back some. The ghetto is being glorified, and there's nothing good about the ghetto except getting out of one.
