Do you remember Steve Martin with his Walk like an Egyptian routine? The main reason it was funny was because of the strange body angles. These angles may have been fine for Egyptian dancers, but hilarious for stand up comics. I do a routine where I do several sick looking Tai Chi moves. The audience can't help but laugh.

Charlie Chaplain used the duck footed stance with his arms at his sides, but hands turned up. He also waddled along. Although, I am not an advocate of using a mirror in public speaking training, this is one time you can experiment in creating funny looking poses by thinking odd body angles.

You'll guarantee more laughs with this technique.
