What makes it "custom designed"? You can't ask for specific text to be put on it, you can't specify the length or width, choose the colors, or anything.

I also love when it's not enough for you to pay for your crappy shirt or hat that's going to advertise their product. You also have to send in proof of purchase of their candy product. We wouldn't want some skater guy who's not really into M&Ms wearing one of their shirts, would we?

Waitaminute, is it a T-shirt if it has sleeves? Isn't that just a "shirt"? Maybe that's what "custom-designed" means.

Um, strike that: I guess they're not calling it a T-shirt.
