Every street festival I go to, most recently the Hispanic festival in San Diego, has multiple vendors selling Che Guava crap. I'm pretty sure someone out there will print up your shirts. Disney would probably be the biggest hurdle (voracious legal department especially when it comes to the mouse) so go with my other idea of putting the fruit in cross hairs with a nice caption . . . or maybe a dunce cap . . . or a beanie with propeller.
