Mickey Rourke at Wrestlemania 25

"...During his post-match tirade, however, Jericho overstepped his bounds. After giving Flair a Codebreaker, the devious Superstar goaded Rourke into the ring. The star of The Wrestler entered the squared circle, but soon decided he’d heard enough of Jericho’s relentless taunts. Rourke, a former boxer, swung a slew of heavy fists at his tormentor, finishing with a punch that dimmed the lights of the conceited Superstar and dropped both him, and his pride, to the mat.

After Jericho regained his footing, he quickly retreated up the ramp, leaving the “Nature Boy” to enter the ring and join Rourke in celebration."
