just read this somewere:

“If you watch the last UFC, this is something nobody knows, the Mirko Cro Cop fight that was on Spike last week - he got kneed in the balls, he went down and said to “Big” John McCarthy, “I’m too old for this shit.” and Big John said “No man you’re fine, you’re fine.” and he goes, “No I should just quit right now.” He said this while he was down and Big John goes, “If you want to quit just let me know and he said no, no I don’t.” So he had 5 minutes to recover and said he was too old for this.”
