22Dropout posted this photo this morning. Notice the little 'Rugby' text in the bottom lefthand corner. The sad thing is, Irish people will buy these.
EDIT: Daniel Sexton points out that the shirts seem infringe on the intellectual copyright of Dara O Briain and his latest tour.
SECOND EDIT: *This photo wasn't taken in England, it was taken in New Zealand. But you know what it, it could have been taken in England. And that's all that matters.
