Don't you just hate t-shirts with pointlessly insulting phrases on them? Or even worse, the ones that have long long paragraphs that repeatedly state that because you are reading the shirt, you are an idiot? Most of my shirts are blank, though I have that "You Know You Are In The Mushroom Kingdom When..." shirt which actually annoys me because everyone has to stop me from moving and read it.
I have iron-on paper, so maybe I'll make one that says "STAND BACK! I know nuclear chemistry!!" or something like that.
So, agree with my loathing of arrogant shirts or present ideas for an enjoyable one, whatever.
