UFC fighter light heavyweight Sean O’Connell not only faced Anthony Perosh at Fight Night Adelaide, he also first faced him down and, then... just flat FACED him at their pre-fight weigh-in.

When both fighters put up their "dukes", O’Connell surprised Perosh by winning an impromptu game of rock-paper-scissors.

Apparently, O'Connell is no stranger to wacky hijinx at weigh-ins, either.
