That's what a couple of my students asked me today.
"Can we bring a camera in and record you while you teach? We want to post it on YouTube."
"NOOOO!" I said.
"But you're funny," one whined.
"I do not want to be on YouTube. If I'm going to do something on YouTube, it will be one of my sock puppet shows."
Sock puppet show to come at a later date.
