Because I'd really love a Magna Carta themed t-shirt to wear tomorrow. Had I organised the half-day off work sooner, I might have sorted something out a bit sooner. But the annoying thing is, the exact t-shirt I'd like doesn't exist, so I'd have to go to the hassle of "designing" it and getting it printed.
I mean, the design bit is already done. It's the following text, in white, probably Times New Roman, on a black background:
"Does Magna Carta mean nothing to you? Did she die in vain? Brave Hungarian peasant girl who forced King John to sign the pledge at Runnymede and close the boozers at half past ten! Is all this to be forgotten?"
...or possibly just the first two sentences. How come such a t-shirt doesn't already exist?
