When you're part of a big ensemble TV cast, there's a lot of downtime on set. While some stars retreat to their trailers in solitude, the cast of 'Glee' has found a different way to pass time between takes.

'Glee' heartthrobs Chord Overstreet and Harry Shum Jr. recently told AOL TV about their favorite game-- "psychiatrist."

"We sit in the room and one person leaves the room and has no idea what's going on and everyone in the room has to come up with a problem that they all have," Shum told us during a recent phone interview. "Then, the 'psychiatrist' has to come in and guess what problem everyone has."

Despite the faux title, the actor says being a "psychiatrist" on the 'Glee' set is not an easy job.
