Pittsburgh 2
Acting on a tip from a well-informed source, I trundled off to Primanti Bros. tonight. The cheesesteak sandwich they sell, from top to bottom, is made up of: (1) meat, (2) cheese, (3) french fries (4) cole slaw, (5) tomatoes. It's sort of a french fry delivery device.
On the menu, it says “PITTS-BURGER CHEESE STEAK (#2 Best Seller).”
I ask: “What's the best-selling sandwich?”
Guy says: “The cheesesteak.”
I say: “But it says #2 Best Seller.”
Guy says: “It doesn't say #2 best selling sandwich.”
I say: “Oh. What's the #1 Best Seller?”
Guy, pleased, says: “Beer.”
Dah-DUM.
As requested by one of my fellow conference attendees: the ultimate in empirical work (via discourse.net).

At Mike Madison's kind invitation, I'm in Pittsburgh. I passed what Mike identified as the largest free-standing Gothic structure in the world. I said, “I know what that is — that's the Cathedral of Knowledge.” Mike said, “No, that's the Cathedral of Learning.”
