Holy throwback. This 15-bedroom, 16.5+ bathroom mansion has a lot of stuff going on, but we need to talk about the giant milkshake in the room: It comes with a whole diner. Bust out your roller skates and poodle skirts, because it's decked out '50s style.

Also on the lot is a mega-garage, a bar that looks straight out of Patrick Swayze's Road House and a game room complete with a skeeball machine. Did we mention the tennis court? You'll never have to leave the house with all that going on.
