(I’m standing in line behind a very well-dressed, mid-fifties lady.)

Lady: “What’s the difference between a 6-inch sub and a 12-inch sub?”

Employee: *shows a 12-inch bread* “Well, this is a 12-inch sub…”

(She then moves her hand to the middle of the bread.)

Employee: “…and this is the size of a 6-inch sub.”

(The lady acts like if she has just found out the meaning of life.)

Lady: “Oh, so a 6-inch is around half the size of a 12-inch sub!”
