My favorite one of these was a game between the Flyers and Devils back in the early aughts.
There were too fans verbally going at it outside the broadcast booth.
During a stoppage in play, you here the one fan say to the other :
"**** you, you ******* fat ****. **** YOU!"
The play by play man obviously knows this just made the airwaves and says :
"Whoops. It's getting a little heated out there. We're sorry about that, folks."
I still have it saved to an old TiVo unit's hard drive.
I fire it up once a year because of how absurd it is, how drunk the guy is, and the awkward response from the Devils' play by play guy.
