Mickey's GitF "Know Your Roots" shirt

[tvguy123]

May not be of a lot of interest but Girl in the Fireplace is one of my favorite episodes of Tennant's era and I have always noticed Mickey's shirt. It has a old school Nintendo controller in the center and underneath it, it reads "Know Your Roots".

Today I just HAPPENED to do a eBay search out of curiosity and low-and-behold I found the actual shirt, 5 available all in size Large.
