Will & Grace - Season 4 Episode 16

Matt Damon makes a guest appearance as a clever charmer named Owen, who's competing against Jack for a spot in New York's Gay Men's Chorus. Truth be told, however, Owen is totally straight and is really after the group's big perk: a summer trip to Europe, all-expenses paid. Jack suspects Owen's ruse but needs proof. How about the hug test? Now a flustered Jack reluctantly turns to Grace to ""in"" Owen. Meanwhile, a scheming Karen tries to pass off an unwitting Will as her lover and not her lawyer when she discovers that she's the object of pity for being single at her own Valentine's Day party
