I ask one of my students to get a plastic spatula.
They walk by with a metal spatula.
Mr. C: No, no metal spatulas.
Mr. C: Because metal on metal is bad. These are Teflon pans, and the metal will scratch off the Teflon coating.
Mr. C: No I said Teflon.
N: Oh I thought he said tampon pans.
Mr. C: No, and that doesn’t even make sense. Tampon pans? Really?
