Brainstorming Sweatpant Designs?

I'm in charge of designing the clothes for my softball team. We've always done sweatpants, and I'd like to do them too, except, it's always pretty much the same thing. "SOFTBALL" or "FASTPITCH" written down the side of the leg and a softball either on the top side of the leg or bottom with the year. Anyone have any unique or cool suggestions for sweatpant designs?
