My neighbour, measuring something on his roof: 36 1/2.

Me: 36 1/2? I WISH!!

My neighbour: No, that's what it says.

The next day. My neighbour is making good progress on his roof.

Me: Lookin' good up there.

Neighbour: Thanks! And how's the roof?

Ok... So you totally missed my "36 1/2" joke but immediately found a double-entendre in this second comment? How do I predict your reactions based on this information?
