Oh, and one more... I won't open my first beer until the Steelers first score.
When I watch the NJ Devils games I have watch the game, the whole game, and nothing but the game. No channel surfing during intermission or commercials. No matter if they are losing 8-0 I still have to watch till the end (for next games sake). If for some reason I can't be there for the beginning (or will have to leave before the end) I will tape the game and avoid going home, radios, televisions, and hockey fans till I am sure the game is over. Also I cannot wear a Devils Jersey if my friends and I play the same day the Devils do.
My grandmother, a died-in-the-wool Yankees fan from Beacon, NY, used to watch all their games in a small room upstairs in her home. If the game was close toward the end and she couldn't bear to watch any longer, she would descend the stairs off the room and sit on the bottom step, listening to her favorite, Phil Rizzuto, describing the final inning or so. I don't know if that technically qualifies as a superstition, but I used to get a huge kick out of this almost daily ritual -- a little old lady sitting on the steps, wringing her hands over a baseball game. For myself, I had a superstition for a while of wearing the opposing team's colors when I was attending games. I stopped doing this when I started getting beat up by the home crowd.
My newest superstition is listening to "Time to Go" by Dropkick Murphys right before I leave the office on gamedays. I still haven't found anything to help the Jets.
