Went to twin drive in in Melbourne many many moons ago, with my then GF and a mate who'd not long become single. I don't recall what we went to see but took a wrong turn (honest we did) and ended up parked, watching Emmanuelle L'Anti Virge, before we realised our mistake.
Well. Poor old mate's getting all hot under the collar because he's not long split up with his girlfriend. A single girl, as in a girl in the car to our right on her own, had all of his fantasy juices flowing full bore. He just couldn't make the move to her vehicle to see if she wanted company!
