Anything with Elke Sommer in it. And I was taking German class at the time (mid sixties). If I had not been ineligible, I would have enlisted in the Army to get a free trip to Germany. But "Says here in your file that you joined up to get posted in Germany..., sorry private, you are going to Nam" - so maybe missing out of all of Elke's hot cousins was not so bad.
And many years later.... FKK's!! Woo hoo!
BTW - props to the OP for thinking up this thread and starting it - I had seen somewhere on here that Ms Smurfy did good brain...
