Superstitions/folklore

[Gophernut]

I do the knock on wood thing all the time. I find my self rapping on the end table when an announcer says something positive about my team, whichever one it may be.
I have 'lucky' shirts.
Sometimes, if I change a channel while watching a game, and flip back something bad will happen. So, I make sure I flip the channels back and forth an even number of times. (This one I even don't understand)
Not a big fan of black cats crossing my path.
I won't let my wife wash my kid's jersey after a win.
If someone leaves the room, and my team does something well, they are not allowed to come back in until something bad happens. And vice versa. Luckily I am a Vikings fan so this rule rarely gets enforced.
