So, say you've always wanted to be on a hit sitcom, but you just don't have time for all those pesky acting classes and whatnot. Well, CBS has your answer.

The network is launching a series of karaoke contests in nine different markets. The winner from each market will be flown to Los Angeles where there will be a final showdown. At that final contest, cast members from How I Met Your Mother will help choose the winner. And that person will get a walk-on role on the show.

Cities, stations, and dates after the jump.
