Matthew Morrison did not escape his appearance on the Tonight Show unscathed. Jay Leno loves embarrassing his guests by revealing old footage from "before-they-were-famous" days, and the Glee star's vintage clip was certainly amusing!

Matthew once made a cameo appearance as a member of a gay boy band called "Boys R Us" in Marci X — a flop comedy in 2003 film starring Lisa Kudrow and Damon Wayans.

"It was the gayest thing I've ever done in my life — literally," the actor explained before the clip, which shows the four band members wearing pastel blues and pinks.

The group can also dance and sing!
