How long is too long?

So I was at this lit party last night in Manchester, a couple of mates run this magazine and they won and award, only they didn't. Anyway that is far from relevant. So I was talking to two girls, Aspic, a mate of mine (yeah she is transparent, and soft when pressed), and a friend of a friend's girlfriend, House (yeah she's massive, fat) and they starting talking about a show that featured the guy who has the longest cock in the world. Well, every guy in earshot catches this, two descend, one of the mag guy mates and some random dork. Of course the guys immediately want to know how long, Down to the knee? How tall is he? and go on to insist that he must be miserable, he must never get it up, ...all that blood in one place? No way! The girls are totally matter of fact in saying that the guy loves his massive appendage, cock-a-hoop you might say, and he boasts that he never has a problem getting a girl. The boys frown, threatened. But the girls are totally adamant that his cock is ...way too much. They even pull faces and screech. Eeeuw!

At this point I drifted off into an interior monologue about how long is too long for my manuscript and associated letter and synopsis to be with the agent guy I sent it to in London? I only posted it last Friday before I set off on the train for Oxford. So less than a week is okay. Two weeks? Reasonable. Three weeks? He should be getting in touch by then, think I'll post him a friendly email, all upbeat, chatty, Trumanesque. Four weeks or longer? Way too much. Eeeuw!
