Stay Calm and Carry On (a British wartime slogan and poster) is a popular thing to spoof lately. Popular enough that even I have a half-done and partially abandoned t-shirt idea along the same idea as this Busted Tees shirt. But like all good ideas, if you have it, do something with it, or someone else will take a crack at it sooner or later. And honestly, theirs works better.
The shirt retails for $16.99 plus shipping. Thanks to Clay for
ruining my shirt! the link!
