How to explain video games to someone who's just recently learned about electricity. "Well, you play them on a computer, like the machines you use to access the network here. Like, for example, maybe on the screen there's a character, and you use the controls to make him jump around and defeat his enemies and rescue the princess. Er . . .

Donatello grins. "You should ask Blades to give you a ride sometime."
