It's the case, it seems, of a guy hiring a prostitute ... who then stole his dog.

Journalist and editor Aaron Naparstek was at the Park Slope Food Co-Op grocery store in Brooklyn the other day, just minding his own business, when he came across one of the most bizarre "reward" posters since Butch Cassidy robbed that transvestite brothel.

The poster says: "Dog thief & guilty of burglary. REWARD of (500$) for any info leading to the arrested wanted for burglary grand larceny. Please call if you see her or dog." Then, tacked on the left side is what Naparstek believes could have been added by a Co-Op staffer: "I hired a hooker and she stole my dog!!!! Waahhhh!!!"

Naparstek wiped out the number and the identifying eyes and hooker stamp, so we were unable to contact the poster, whose first name appears to be John, for comment or an explanation. Naparstek may be on to something with his observation on the "hooker" tag: We're not entirely sure this is real.

First of all, how come there's no mention of the dog's description? How is anyone supposed to spot the dog without knowing what to look for? And whoever heard of a hooker posing for a photo before having sex with her? Sure, maybe this is the photo she advertises with, but that sad stack of boxes and CDs in the background just reeks of "bachelor pad."
