I have moved the GIF below the page break to spare the sensibilities of certain visitors to IM.
The caption contest is for those with a rather adult sense of humor, though to be honest the GIF itself is really PG, it is only our filthy minds which makes us see something that is not necessarily there.
So before you proceed keep in mind this might not be your cup of tea if you are easily disturbed by photoshop, or get queasy on the merry-go-round.
