Open wide

I see this sign a couple of times a week and it always makes me laugh.

The relationship between the text and the two figures is elusive--are they swallowing the words, or did they just cough them up?

The latter, I think. It feels more meta. "Regurgitate nothing," says the sign, which was itself regurgitated. A text fit for a graduate level literature course.

Or, me, hurrying to my bus and chuckling.
