I found this description online, I guess it is that "sport":
American Football takes on average about 3 hours to complete and has about 12 minutes of actual ball in play action (The average NFL game contains about 120 actual plays, which take an average of six seconds each. That's 720 seconds of play, or 12 minutes). That means that only 5% of the game is action and 95% of the game is the borefest of standing around, scratching and slapping butts, getting off and on the field and endless commericals for viagra and cialis. You spend 5 seconds watching action by which I mean fat guys in pads and lycra tights pushing each other, then minutes of complete boredom followed after.
