So this professor comes up to me and says he needs a three-ring binder, but he couldn't find one in the workroom. I grab my master key and say, "Okay, let's look in the storage room!"
"You guys have a secret room back there?"
"Yeah. It's like the BatCave, but without the T-rex and the giant penny."
No, I have no idea why I continually say these things to non-geeks.
