Memorable ''Will & Grace'' guest stars: Edie Falco and Chloe Sevigny
As apartment ''flippers,'' Manhattan Westsiders Will (Eric McCormack) and Grace (Debra Messing) meet their match in Deirdre (Falco) and Monet (Sevigny), a rival real estate/interior-design team from the tony Upper East Side. Oh, they're also a lesbian couple. This 2004 episode sees the two competing pairs fight an escalating war of sexual divide-and-conquer, one that nearly finds both Will and Grace, um, switching teams. Neither Falco nor Sevigny has ever been more alluring, but in the end, nobody flips to the other side.
