Two and a Half Men

Recap

When Chelsea's old college roommate, Gail (Tricia Helfer) breaks up with her boyfriend, Chelsea tells her she can come stay at Charlie's Malibu beach house.  She's hot, so who's Charlie to complain.  He ends up having fantasies about a three-way and can't trust himself around Gail when Chelsea goes to work and leaves them alone together.

Berta suggests to Charlie that he gets rid of her using the best tool he has... his brother.  Charlie convinces Alan he has a chance and he goes to talk to Gail... scaring her away within minutes.  Chelsea goes into Alan's room that night and reams him out, creepily turning the guy on.

The episode's title, "Gorp. Fnark. Schmegle." is what Alan is thinking in his head when he's busy drooling over Gail.  The original episode title, "The Moustache Attachment," was mentioned by Berta when she thought about how she'd still do Gail if she painted on a 'stache.
