Matthew Morrison, better known as Mr. Schuester on 'Glee,' got in a battle on 'Oprah Winfrey' (weekdays, syndicated). A dance battle, that is.

Morrison busted many moves, including break dancing, in a dance battle against Harry Shum. "Hey, Mr. Schuester ain't backing down to nobody," Morrison said to Shum. Shum took that challenge and popped and locked Morrison into defeat.

You did your best, Mr. Schuester, but you got served.

Watch the video after the jump.

The Teen Choice Awards will feature a dance battle between two of the toughest, roughest, street-est (not a word, I know) dance crews around. No, Lil C and his crew won't be there crumping. Miley Cyrus and Mandy Jiroux's M&M Cru will battle ACDC, the dance crew featuring Jon M. Chu and Adam Sevani of Step Up 2: The Streets. The two crews are BFFs and they challenged each other back in April. A more heated rivalry has not been seen since TuPac and Biggie. Yeah! Totally street. "Street" is even in the name of the movie.

The Teen Choice Awards have some other performers and appearances lined up too. But they're not "street" so who cares? Shia LaBeouf, David Archuleta, James Marsden, Sophia Bush, Josh Holloway, Scarlett Johansson, Zac Efron, Pink, JoJo, Kristen Bell, and Hayden Panettiere are some of the other names previously announced. Mariah Carey is slated to perform her new single, "I'll Be Lovin' You Long Time."

The Teen Choice Awards will air on August 4th at 8 p.m. ET/PT on Fox.
