A linguistic joke: Artists' Canvas

Contributed by Jim Brockman:

I used to work in an art supply store. We sold artists' canvas by the yard, and you could get it in either of two widths: 36 inches or 48 inches.

Customer: "Can you please cut some canvas for me?"

Me: "Certainly, what width?"

Customer: (confused and slightly annoyed) "Uh, Scissors?"
