Oh yeah, that's right. The crowd always got more silent when Earl Weaver, Billy Martin, Lou Piniella was arguing with an umpire while using G-rated language. And arguments and manager meltdowns are almost never shown and celebrated by giggling hosts on SportsCenter.

Get off it and watch a sporting event once in a while. Check out a hockey game and watch players mouth off to each other from bench to bench. Football players on the sidelines (other than TO, too!!) aren't exactly Captain Kangaroo material. It's the intensity of competition that necessitates an outlet like that. Plus, I'm not entirely sold on the audibility of the "bomb".
