Professional athletes face a ton of scrutiny on and off the ice, so it certainly wouldn't be out of the ordinary for them to have to deal with someone heckling them from a moving vehicle.
While driving in downtown Vancouver, former NHLer Paul Bissonnette spotted Manny Malhotra walking down the street. Being the all-around entertainer that he is, Bissonnette rolled down his window and surprised Malhotra by acting like a heckler.
You could tell that at first Malhotra may have thought that he was actually dealing with a real unruly fan at first, but once he recognized that it was Biz Nasty, he proceeded to show off why he was one of the most likeable players in the league throughout his career.
For those thinking of trying this out for themselves when they run into a pro in the streets, remember that knowing the person in real life goes a long way in it ending up as a pleasant interaction.
