How did you start doing stand-up?

I often found I would say something "in situ" (Do you like that word? That's a $64,000 word.) that would crack everybody up but I didn't know how to present the same idea in a stand-up comedy context. I took a course with the great Stephen Rosenfeld in New York. He did a workshop that really helped me get those ideas onto the stand-up stage. And it's the format that I base my workshop on. Thanks Stephen. (In fact I still study in bits and pieces with Stephen when in NY.)
