I don't understand The White Stripes. What's with the red and white "Say Yes to Michigan" T-shirt? Don't you know school colors and rivalries?

I can do without seeing extra people wearing red and white. Why not black and pink? It's slightly interesting but also lame to try to get attention by being about a color... or two colors. I realize that's probably the point, but isn't it even tired to be making points about one's own lameness by now?
