“To the lease holder of Kryten 2X4B 523P.” That’s your full name?

Lister: “To the lease holder of Kryten 2X4B 523P.” That’s your full name?
Kryten: Yes, but personally I don’t much like the 2X4B. I think it’s a jerky middle name. Still, it could be worse. I once knew an android whose middle name was 2Q4B. Poor sucker!
