I liked Patty because she seemed more promiscuous.
No ****, Sherlock. She lost control over a hot dog, for crying out loud! A HOT DOG!
So not only are these two girls just pure genetic aberrations that would have generated TONS of media attention even back in 1963 (because identical cousins just really aren't possible), but Patty likes to rock and roll and she gives it up over a HOT DOG? Cool your jets there, babe! Geez, how loose was she that she lost control over a HOT DOG? Clearly the rapid onset of several STDs would diminish the identical traits in them, and very soon. No wonder there wasn't a fourth season. Probably due to a rapidly developing case of syphilis. What a crazy pair!
