Something you don't see every day

So I'm having Beers on the Bridge with my co-workers (a Friday evening institution - gotta love the lax public drinking laws in this country) when one of them says, "So, did you see the guys over there, playing the Blue Vein flute?"

Sure enough, in the corner of the plaza were two drunk guys hopelessly trying to dry-hump each other. They were rolling around for a decent half hour in what looked like a slapstick hybrid of a Matrix action sequence and Christiane F. Definitely not one for the kiddies.
