Chevy Chase earns a solid "B" (not a "C") for his rock band debut

For my money, the funniest moment in NBC's two-hour comedy block last night came during Pierce's (Chevy Chase) college rock band debut, playing keyboards and singing backup to Vaughn's woeful song of heartbreak (and moving on), "Gettin' Rid of Britta."

The lyrics are clever, and Vaughn is easy on the eyes in that sensitive musician kind of way. Rocker Vaughn won me over with lines like, "It isn't like I would ever hit her, but I would sell her to the highest bidder." But it's Chevy chiming in with "she's a no good B" and "she's a G D B" while jamming on the keyboards that had me cracking up -- and watching over and over and over again.
