It's kind of like the buffalo sentence:

Except nobody ever verbs "buffalo" unless they want to say *that* sentence, and then they never verb it again. So this is almost better. It's a more legitimate verb, though a lesser known proper noun, and unfortunately the singular and plural forms don't sound alike.
