Of all the fantastic characters on the brilliant HBO comedy series, “Curb Your Enthusiasm,” the one I can never get enough of is JB Smoove, the innovative comic who plays Larry David’s best sidekick, Leon Black.

Here is an insidery, slightly tasteless, but decidedly funny spoof video of Smoove taking over Hollywood’s William Morris Endeavor talent agency on Yom Kippur, the Jewish holiday.

In it, Smoove decides to “run sh*t!“

And so he does:

So here’s the hysterical spoof from “Saturday Night Live,” in which his comic double unveils the iPhone.

Very funny:

This is a very funny CollegeHumor video series, called
“Always Open With Dave Koechner,” a great if unsung comic. It is set at a Denny’s restaurant. Really.

This perfectly awkward episode features another comedy gem, Amy Poehler.

Maybe it is just me, but a lot of these small Web-only videos are really starting to get interesting.
