'Glee' can be frustratingly inconsistent, but you've gotta hand it to them when it comes to casting. The latest addition? LaMarcus Tinker, who was wonderfully understated as Travis' roommate Kevin on 'Cougar Town' last season, and also won our hearts as Tinker on 'Friday Night Lights.' This season on 'Glee,' he'll have a recurring fling with Mercedes (Amber Riley), who is frequently underserved on the show.

'Glee' Season 3 premieres Tues., Sept. 20, 8PM ET on Fox
