Went as part of my cousin's bachelor party, and it couldn't have been better.
Valby clearly has years of experience working the crowd -- and he wasn't afraid to tell the sound and lights guys adjust levels for maximum enjoyment ("can you turn these lights off back here -- they f*** with these guys in the front row")
Be prepared for an extremely dirty show -- he'll make fun of everything and everyone, so don't bring your mother.
I would definitely see this again, and would bring everyone (except my mother)
Croc. rock cafe was great too -- a dive, but in a good way. Don't expect doilies and teacups, but at least the floors aren't (too) sticky. Really though, a perfect venue for this kind of show.
