I got a shirt that says the same thing, but I got it last year when I went to see McBeth at the Stratford Festival (It is a theatre festival held annually in Stratford, Ontario, Canada). The McBeth shirts were way too large for me, so I got one from Midsummer Night's Dream.

Also the shirt I am wearing now is my current fav, because it is not too baggy and it conforms nice enough to my body that it does not show my stomach which is a flabby.
