"Mad Men": Pete, Trudy and Ken bag it in Vegas

I can totally see Pete Campbell going whole-hog for something like this.

"Mad Men" players Vincent Kartheiser (Pete), Aaron Staton (Ken Cosgrove) and Alison Brie took (Trudy Campbell) took part in TBS' Comedy Festival festivities at Caesars Palace this weekend.

Specifically they were contestants in Friday's "Celebrity Bagging Contest," held to promote the wacky TBS latenighter "10 Items or Less," a semi-improv skein set in a supermarket.

The "Mad Men" trio didn't win, but from the looks of these pics they had fun, and I'm guessing they all got to spend a weekend in Vegas on Time Warner's tab.

For the record, the winning team was John Lehr, Kim Coles, Robert Valderrama and Greg Davis Jr. from "10 Items." Sound fishy? Nah. The grand prize was a donation of $500 for DoSomething.org, a non-profit outfit that aims to encourage young folks to take action on causes they believe in. And all the food used in the bagging competish went to a Vegas food bank.

Fresh segs of "10 Items or Less," produced by Sony Pictures TV, bow Jan. 6 on TBS.
