To say whatever nonsense comes into your head without any repercussions has got to be a bigger high than heckling a movie screen in a darkened theater.
Stand-up used to be much more of a form combat. Heckling was much more common [in the '90s]. And I couldn't get stage time, and so I would go out to Pip's in Sheepshead Bay.
Every week for me was the same audience, and every week they heckled me. The better I got at comedy, the better the audience was at heckling me. But it helped me with my joke writing.
