His channelled his rage into the unpredictable character and one monologue that was cut from the final edit saw Jeong delivering a caustic rant.

The actor accepted his MTV award after learning that his wife was cancer free. She has now been all-clear for six years. 

"She's just a pillar of strength," Jeong said. "She's my biggest inspiration because she handled it with such grace and strength and class. Even if I wasn't married to her, I'd be in awe of her."
