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.
