Unstealthiest Ninja T-shirt. And the writeup is as funny as the shirt:
"Your master said you were the best at arterial spray in the whole dojo. Every slice of your blade brings gushing red joy to his old eyes. That counts for something, right?”
“Yeah, maybe. But stealth! Why can’t I get stealth down? Who ever heard of a loud, clumsy ninja? I dunno. Maybe I made a mistake. Maybe I should’ve gone into accounting like my parents told me to."
ASM826 needs one of these, bad.
They have a bunch of others, that are equally funny.
