(As someone NOT into it.)

Apparently, there was a pony at some petting zoo. A pretty pony, of very gentle temperment. Its job was to give rides to all the little kids who came to the petting zoo.

Well... apparently a guy who was in the country illegally was spotted "Making Sexy Time" from behind with the pony in its off-hours.

I don't remember all the details of the story, but me being me, I added a comment to the long list of other replies, and was rather proud of my response:

"Neigh means neigh."

I am sad to report, my brief and honest comment was removed, along with about 70% of the other ones.

So it goes.
