The March 25 episode of "How I Met Your Mother" won't mark the first time the show has played with time-travel (See: Season 5′s "The Window") but it could be the greatest!
In the episode, Ted will meet future versions of himself and Barney, who show up to try to convince him to attend Robots Versus Wrestlers. (See an exclusive photo below.) As we know, this isn't the first time Ted has been reluctant to attend the awesome-filled event. Back in season 5, he ditched the event -- missing the chance to meet his Mexican wrestler doppelgänger -- and instead chose to go to a fancy party. Lame, Ted. Lame.
