Many nationally touring headliners agree: Houston's comedy scene is prodigious. On Mondays, the Laff Stop is the place where local comedians gather to work on their craft. You'll see the whole range, from nervous wannabes reading from notebooks to seasoned professionals trying out new material. They're five minutes apiece, so you won't have to suffer long, and you're guaranteed at least a couple of good laughs. Like everything popular these days, they've added a sequel, Open Mike II, on Thursdays. And with no cover charge or drink minimum, the price is right. A number of the club's headliners -- Louis CK (Chris Rock's chief writer), Wanda Sykes, Mitch Hedberg and Joe Rogan, to name a few -- have been known to do some time on the small stage the week they're playing the club. The only thing you'll be risking is a round of payback should you decide to heckle the wrong comic.
