Next Door Neighbor

Listen up, buttercup. This joke is dark. The dude starts off talking about how there's a bunch of weirdos living next to people, then implies he's one of them because he's got the hots for his 10-year-old neighbor. It's supposed to be funny because it's so messed up. Also, the joke is that the person thinks the boy is attractive. Your brain is as smooth as a bowling ball if you didn't get that.
