Diane: Wine cellar? Since when have we had a wine cellar? Vodka rocks, please.
Sam: On your day off, I had a couple of workers checking the plumbing, and they discovered that there was a staircase behind the wall in the closet there.
Diane: That's amazing. You mean it's just been there all this time?
Sam: Yeah. A long time ago, when this was just a private house here, the owners used to keep their crazy old grandmother down there. They say that if you're real quiet, you can hear her chains rattle. Supposedly, she swore to seek vengeance on blond waitresses. Mwuah!
Diane: Very funny.
