When is JB Smoove himself and when is he Leon Black? I guess that depends upon whether you can tell when "The Ruckus" is upon us.

As I learned the other day in Chicago, in the rock garden outside the Westin River North Hotel, it doesn't take much to get JB Smoove on a roll. Here he is delivering some life lessons to me, or should I say, handing me my ass in an interview. Know what I mean? Roll the clip!

I cut the clip into two parts, and as we continued, he also demonstrated why every person is unique, and instead of going with the snowflake metaphor, JB Smoove shows us how God uses his own pottery wheel. He also contemplates the difference between snot and tears. You have to see him to believe him!

If you enjoyed that, then you'll be sure to enjoy him when he performs June 23 on TBS as part of Cedric The Entertainer's Urban Circus, and in July, when he hosts Russell Simmons Presents Stand-Up on Comedy Central.

JB Smoove also will be hosting a live video chat tonight — 9 p.m. Eastern, 6 p.m. Pacific — with fans of Curb Your Enthusiasm to talk about his character, Leon Black, and the TV Guide panels that discuss the Curb repeats. Go to: http://www.ustream.tv/tvguide
