What a nightmare!

H told me a really good joke last night:
A lawyer, a policeman, and an academic are discussing whether it is better to be married or have a temporary relationship. "A spouse is better - you get stability", says the lawyer. "No, a girlfriend is better, I don't want to be shackled to the same person", says the policeman. The academic says: "I have both. I tell my wife I'm going to spend the night with my girlfriend, and my girlfriend that I'm spending the night with my wife, and then I get to work all night."

I thought it was brilliant!
