STAGE TUBE: Megan Mullally Performs on ABC's HAPPY ENDINGS

On last night's episode of HAPPY ENDINGS, guest star Megan Mullally playEd Penny's perpetually optimistic mom who was in town for a singing gig at the boat show. Her enthusiasm inspired the gang, but when Penny found out she was hiding some less-than-happy news, she decided it's time to give mom a reality check.

ABC's HAPPY ENDINGS tells the story of a couple who split up and are faced with the real question of who gets to keep the friends. 

The breakup, in the words of one pal, was a "huge game changer" that complicated everyone's lives and made everyone question their own choices. Alex and Dave were the glue that kept their urban family together: Alex's sister, Jane, a suburban housewife, and her buttoned-up husband, Brad; Max, their perpetually underemployed gay friend; and Penny, who worries about never finding the right guy.

A year later, this gang is still friends, although Alex and Dave are trying to figure out just where their relationship stands. Penny is convinced that 2011 will be "The Year of Penny," and she starts things off by buying her dream condo. She'll also be getting a new roommate when Alex moves in. Max may make the biggest change of all when he does something his friends never thought he'd do... get a steady job.
