It's Season Three and the search for a soul mate has never been so wildly inappropriate! Thirty-year-old Ted is still looking for Miss Right, but his road to domestic bliss is improbably paved with punk rock girls, tattoos, adult video expos and an epic St. Patrick's Day bender. Meanwhile, as Marshall and Lily adjust to the quirks of married life, the outrageously incorrigible Barney commits a major violation of "The Bro Code." Plus, Season Three features a host of hilarious guest stars, including BRITNEY SPEARS, SARAH CHALKE (TV's Scrubs), ENRIQUE IGLESIAS, MANDY MOORE and supermodel HEIDI KLUM.
