With all of this secessionist politics in the news, you might want a t-shirt like this to voice a more united position. A number of years ago the paleobotanists had a button that said "give Pangaea a break", and this is the same joke just from a different perspective. Of course it would be more appealing if they had spelled Pangaea correctly. After all you wear such a shirt to look a bit clever, but in this case, not.
