Ideas for Sport Themed T-Shirts

So, I have a few ideas for t shirt designs that I figure I might as well write about. I like to think that I'm a funny guy when it comes to designing shirts, but I'm pretty sure that that is not what people are looking for here. Anyway, without further ado, some of my designs might be a bit strange, but bear with me.

A lot of teams have animals in their logos, so why not take advantage of that, and make the animals look vicious, angry, or even cute and cuddly. The combinations here are endless. You could hire a freelance artist to take the original animal, and make weird, or wacky versions of the original logo, pay them for the use of their design, and throw it on a shirt. If the art is original enough, the shirts will sell well. Can you imagine an Arizona cardinal with a worm in its mouth? I know I can.

Also, you can use the competitive spirit of sports fans to create anti-sports logos. Have you ever seen the back of some trucks where they have a sticker depicting a small cartoon type character urinating on the word "Ford" or "Chevy"? Take this idea, and modify it for your own needs. You don't have to use the same cartoon character urinating on your least favorite team's logo; another good idea would be to depict one team logo against another. Even multiple team logos that look like their "ganging up" on an unsuspecting victim. The ideas here are endless.
