Skin Deep

Him: I always get this red mark on my nose if I get too dehydrated. It's weird. Even my dermatologist couldn't figure it out.
Me: Wow. Crazy. I always get a red mark in the same spot, but it's cuz my nose is skinny so my glasses dig into it there.
Him: Well, you DO have Skinny Nose Disease.
Me: Yup! And you have Water Bindi Disease!
Both: Bwaaahahahahahaha!
