Punk master Ashton Kutcher rules! He really made SNL enjoyable to watch this past weekend when he mocked Kevin Federline by donning "Federline underwear" for a skit. Ashton played the talent-challenged Federline, basically looking greasy and dirty in nothing but tighty whities.

Rolling around a bed wearing a white pair of briefs with 'Federline' emblazoned across the band, Kutcher blasts, "I look like I might stink, yo, but I don't...
"Britney thinks I look best in my underwear. By the way, Britney keeps her underwear over there and over here, and over there in that big pile. Most of the time she keeps 'em in my mouth." Hilarity ensues!
