I've been doing stand-up for so long, I think 19 years, that I love topics I can also expand on. Once I identify a topic like, say, seafood, which is a big one right now, it's like there are different kinds of tangents I can go on to build a larger chunk.
Truth, I have learned, differs for everybody. Just as no two people ever see a rainbow in exactly the same place - and yet both most certainly see it, while the person seemingly standing right underneath it does not see it at all - so truth is a question of where one stands, and the direction one is looking in at the time.
