Me: Get out the magic dartboard. "Let's see ... Hermione Granger." *throws dart, hits a 3. "Well, that's a D. Now, Neville Longbottom." *hits a bullseye* "Full marks for Toadboy."

And also from jkmoreno, in the chat that the above came from: At least Lockheart was good comic relief cause you could laugh about how much he sucked and how all the other teachers probably wanted to beat him down. I'm sure Flitwick could charm a boot to repeatedly kick Lockheart in the ass for the rest of his days.
