As happy as 'How I Met Your Mother' and Joe Manganiello fans were happy to see Marshall's law school buddy Brad return to the series in Monday's "The Stamp Tramp," something definitely felt amiss.  Sure the fit and confident Brad turned out to be alive and well underneath a fat suit, but what happened to the character's good nature?  Would he really sell his former brunch buddy out like that?  Watch a new clip from "Twelve Horny Women" to find out!

After years of playing the chiseled, but sensitive werewolf Alcide Herveaux of 'True Blood,' there's no way Joe Manganiello would ever play a villain, right?  That's certainly what it looked like when his 'How I Met Your Mother' character Brad revealed his deception to Marshall, nearly costing him the case of his career!  But when last we saw Manganiello's Brad in season 5, he and Marshall were the best of bros!  Whatever could have happened?

Courtesy of CBS' latest clip from next Monday's "Twelve Horny Women," the bro-tastic barrister reveals the cause of his fat suit fake-out, and has some wise words for Marshall as well.  Will Marshall ultimately triumph over Gruber Pharmaceuticals, jump-starting his career in environmental law?  Will the two ever be able to share a bitchin' brunch again?

Watch the latest clip from 'How I Met Your Mother's "Twelve Horny Women" below, and give us your predictions on the (potentially) final season in the comments!
