Skull! Is it mine? Is it yours? What teacher will it be…?

Alas poor Stueve! I knew him, Horatio:

“A fellow of infinite wisdom, of most excellent knowledge: he hath
taught me a thousand matters; and now, how
abhorred in my imagination it is! My gorge rises at
it. Here hung those lips that I have heard speak I know
not how oft. Where be your words now? Your
lessons? Your teachings? Your flashes of merriment,
that were wont to set the classroom on a roar? Not one
now, to mock your own grinning? Quite chap-fallen?
