Help?

My father has asked for exactly one thing all year, and I have been unable to find something even close. I looked for his b-day in August to no avail, and now can't find it for Christmas either.

The U of MN had t-shirts this year for various sports (basketball started it, I think) that said, "No More Minnesota Nice" on them. I cannot find them anywhere. They may have been the ones that come with the student tickets, but usually you can find them or something similar after the tickets sell out. This year? Zip.

I have googled. I have looked at the U of MN online sites. I have looked at Etsy and Cafe Press. No go. Anyone have any suggestions? Please and thank you?
