The Butler Did It

I don't know anyone who is a butler and I don't know anyone who has a butler, but I've read that enrollment in butler-training schools is very high. We occassionally have an imaginary butler, but he's more of a menace than an apt assistant at managing household chores. For example, if someone leaves milk on the counter overnight but no one fesses up, I might say:

"Perhaps Hobbs did it?"

Or if we're watching TV and no one wants to get up to get the cookies from the pantry, I'll say:

"I think Hobbs is off tonight."
