Exterminators

This morning, while driving Tyke to his trumpet institute at the university, we got stuck behind a large commercial diesel truck for a while. We were listening to NPR and I forget the context, but the speaker said, "They'll have to call in a fumigator." After a couple of minutes we started moving again, and

Tyke: Mom, is a fumigator an alligator that eats fumes?



Yeah, kind of like the opposite of a fire-breathing dragon.
