I remember discussing this once back at Georgetown, but I have forgotten most of it.

Two questions-- what about wake/woke? That one always bothers me. The end of To Kill a Mockingbird sounds so wrong, and yet, in a way, it's also right.

The other one is drink/drank. I know that it should be drink/drunk, but because drunk tends to be an adjective, drank seems to have taken over as the pp. That one might be interesting, because while it was already strong, it changed forms to another irregular, you know?

The obvious one is spit/spat, though.
