It probably isn't the best idea to p*ss off a pumped-up rugby player.
But that's exactly what this streaker did during Leicester Tigers' clash against London Welsh on Saturday when he decided to strip off and run across the pitch.
London Welsh star Chris Hala'ufia didn't take too kindly to the interruption, and floored the invader who left the field in a daze.
Hala'ufia, presumably still wound up by the incident, was later sent off himself for a dangerous tackle on an opponent.
