Cuz you have TV. Jerk. You're like the guy who buys all the land around the Oasis and then turns innocently to the crowd of thirsty people behind him and asks, "Oh, did you guys need something?"
I gotta say, personally, that I *hate* watching TV's at bars/pubs. I go to hang out with friends, make jokes, hear music, get drunk.
I guess if its a really big game that I have no rooting interest in it's sometimes fun to watch at a bar w/ other folks.
But Celtics games? I'd rather hear the announcers (hopefully Tommy/Mike) at home where i can yell, scream, thrwo things, pound the couch, etc.
