Mouse is leaving his comfy burrow for the bright lights and big smells of the City. Having been very discrete about telling his co-workers (Megaphone, rooftop), he decides to lighten the mood with a few jokes...

A few doctors go out on a duck hunt together... each has their rifle and is looking to bag a prize bird
The first duck goes flying past, and the GP lines up to shoot it down. He thinks it's a duck, but wants to ask a specialist just to be sure
The psychiatrist looks up and thinks, "I know it's a duck, but does it know it's a duck???"
The surgeon looks up, shoots the duck and turns to the pathologist and says, "Be a sport, go over and tell me if that was a duck"

Two doctors are at a conference eyeing each other up... eventually they pluck up the courage to talk to each other and agree to go out on a date... They have a wonderful dinner and end up back in the hotel suite... One thing leads to another as things often do, and they end up in bed. After the love making is finished, he looks at her and says
"Can I ask you a questions?"
"Yes" she replies
He asks, "Are you a surgeon?"
She says "How did you know"
"It's because you're always washing your hands" he notes
Then she asks "Are you an anaesthetist?"
He replies "Yes, how did you guess???"
She bluntly says "Because I didn't feel a f**king thing"
(Thanks to Faith Walker for that one)

A GP, an anaesthetist and a surgeon all die in a plane crash, on arriving at the pearly gates, St Peter informs them that they must justify their lives to God in order to enter heaven:
GP: Well God, I've lived a humble life serving my local community, making their lives better to the best of my ability and been at their beck and call 24/7 for the last 30 years
God: You have lived a good life, come sit beside me
Anaesthetist: God, I've spent my whole life easing people's pain and saving those who no one thought could be saved.
God: Indeed you have, come sit beside me. Now you (points to the surgeon), what do you have to say?
Surgeon: You're in my seat
