Joke of the week that starts out good, but the punchline falls flat, then you realize that the joke is pretty funny regardless...

A guy is driving out in the middle of nowhere, very lost. Finally he spots two houses, so he goes up to the first house and sees an old lady yanking on her boobs and an old man masturbating. He is so freaked out that he goes to the next house and says, “What’s up with your neighbors?” And the owner of the house says, “Oh, that’s the Robinson’s. They’re both deaf.”
