Of course, being Mickey, he wasn't going to make the process easy:

"Ok, fine, but I get one banana slice for this--and put away that camera, for cryin' out loud!"
Terms were agreed upon, and so he picked a slip (or more accurately, grabbed and tossed one), and so our winner is: The human (aka Buttons' mum).
Congratulations, my friend--please email me (firstname.lastname@example.org) with your mailing address so I can get your new calendar out to you (and international mailing is not a problem).
Thanks lots to everyone who entered--this may be my first giveaway, but it won't be my last. :)
