WATCH: All of Sean O’Connell’s hilarious weigh-in antics in one 20 second video

Weigh-ins can be bloody tense affairs.

Fighters are drawn out from the weight-cut, they're in the frame of mind for combat and they have the pressure of the crowd watching how much of a fearless front they put up. That's why we're all for fighters just having a bit of craic, something that Sean O'Connell has a bonafide black belt in. The 17-6 light heavyweight has fought four times in the UFC and he has shown off some bit of banter at each and every weigh-in. Whether it was the rock/paper/scissors before the Anthony Perosh fight or the "boop" on Matt van Buren's nose, hilarity is guaranteed when The Real OC is around. https://youtu.be/w7uKx7YMYgY
