A comfortable pause.

"Quantum materiae materietur marmota monax si marmota monax materiam possit materiari?"  This in a deadpan delivery by a Clarice long accomplished in Classical Latin.

A shared look.

(I couldn't resist.  The other ending was dramatic, but somehow…unsatisfying.  I believe they laugh—a lot.  The doctor does like his fun, and it *was* 'prescribed' to Clarice…)

a tergo --from behind quod licet Iovi, non licet bovi --what is permitted to Jupiter is not permitted to a cow Quantum materiae materietur marmota monax si marmota monax materiam possit materiari? --How much wood would a woodchuck chuck if a woodchuck could chuck wood?
