Many years ago the Philadelphia Flyers were clobbering the New York Rangers in a playoff series.... One game (might've been the last in the series) was tied with under a minute to play and Eric Lindross and John LeClair got a breakaway which ended with LeClair passing the puck across to Lindross who put it in the net behind Mike Richter for the win.
As Richter headed for the bench the camera was on him and even with audio to go along with the picture my eyes started to bleed from the violent stream of expletives coming from his mouth!
The announcers comment at the time was: "Now, what Richter's saying here is that he overplayed John LeClair..." and my three friends and I looked at each other and all said "Oh! Is THAT what he said!?!"
We've since realized that for some reason many athletes actually use John LeClair's name in vain when bad things happen.... Just read their lips and you'll see, too!
...And so to this day "John LeClair!" has become our favorite expletive.
