Heh. Out here in Oregon we have a Chicagoan who has a beef stand. One time I heard him telling a customer that he could give him a ketchup bottle, but he could not put ketchup on his hot dog.
Anyhow, I object to any cheese on an Italian Beef. :-)
I asked for ketchup in the Texas Chili Parlor once and the guy said "there is no ketchup in the building."
Then the guy I was there with said "if I ever have you over for chili and you put ketchup in it, I'll never have you over for chili again."
