Strange Bedfellows

S2 E17: Eager to make a difference in the world, Christine volunteers to collect signatures supporting an issue she doesn't quite understand--as she finds out from a competitive signature-seeker, Audrey (Sandra Bernhard). Meanwhile, when Richard learns that Barb (recurring guest Wanda Sykes) and Matthew once kissed years ago, Barb demands an equally embarrassing secret from Richard as insurance that he'll never tell Christine. She learns more than she wanted to know.
