MBLAQ's Mir showed off his stamina or lack of thereof on 'Star King'!

During the 'campus king' special, Mir attempted to break 15 chopsticks in half with his butt. While MC Boom was getting him set up for the challenge, Mir seemed to be sweating bullets as he kept repeating, "It feels weird." 

Mir grabbed the pole and pushed with all of his strength to break the pile of wooden sticks. But he couldn't help to bring everyone to laughter as he kept trying and trying to no avail and eventually dropped to the floor in pain. 

Ouch! That's got to hurt! 

Mir was also involved in tons of other 'Star King' antics today.
