I made this earlier today. It's based on what that crying wrestling fan said (just look up the video, funny as hell). I made this using an old WWE photo of Shawn Michaels doing an elbow drop onto Triple H from the top rope as a template. It came out a lot better than expected:

You can get this version here or you can pick up the inverted version for darker colored shirts here. I am also considering making a version where everything is outlined as opposed to filled in like this. When I make those, I will update this post. Let me know what you think.

it's photoshopped in the sense that they have pics automatically positioned/adjusted on a shirt as you're creating the design.

yeah, you can make a whole bunch of stuff and sell it (hats, bags, t-shirts, ties, mugs, etc), while also setting the royalty percentage you want to make (minimum is 10%; average amount of money you make for a standard t-shirt, for instance, is about $1.59 if you set it at 10%; I usually keep my royalty percentages at the lowest setting so I can sell it at the cheapest price). This is what we use for the PS3Blog.net t-shirts and stuff as well.
