How Much Is Too Funny, Or Not? ("I, Comic")

As modest as I can be, there is only only way to tell this story. It would be easier for me if someone else, a friend perhaps, would write the following. A third person. Easy enough for me to conjure up. But here I go:

I'm funny. At least I can be when I decide to go there. After friends, or those who do not know me, recover, they might say: "You should be at Yuk Yuk's (Comedy Club)"; "You should be doing comedy"....

The problem is, when I get on a roll I don't always know when it's time to stop. Pushing the boundaries. (Sometimes.)

A "comedian" must know when to stop. More importantly. A comedian must know his audience.
