— Hi, I called you folks with a problem with XYZ, and I talked with a nice man named William who straightened it all out. But I have another question. Can I speak with William?

"Okay, let me see if William is available." The product support engineer brings up the customer's service record and looks at the name of the support engineer who handled the earlier call: billg.

"Yeah, um, I'm sorry, but William is not available right now. His friends call him Bill, by the way. The person who helped you last time? That was Bill Gates."

— Oh my God.
