All the bits that we just know were in the script but sadly ended up on the cutting room floor. Plus, I can just imagine Benedict and Martin saying these things when they know the take is blown!
SHERLOCK
…quite correctly, I'm afraid. Plus, I find you quite attractive with your boyish charm, coupled with your military bearing. I bet you'll be quite dominant in the bedroom which I love, and I know that you find me attractive from the way that your breathing increased when I approached you and you were obviously aroused. That's enough to be going on with, don't you think? Oh, and I hope you like riding crops! The name's Sherlock Holmes and the address is 221b Baker Street. (winks, clicks tongue, blows kiss, exits through door)
JOHN
Of course, we'll be needing two! Where else will we put the restraints and other bondage equipment?
SHERLOCK
It's a three patch problem.
JOHN
My God, you're really exquisite when you lay there like that. I could just come looking at you. (tosses cane and throws himself down on top of Sherlock)
SHERLOCK
...I consider myself married to my work, and while I'm flattered, we could never be more than friends with benefits.
SHERLOCK
Mrs. Hudson! Doctor Watson will take the room upstairs because he thinks I'm incredibly hot. We're out of breath and sweaty and I think we're about to shag each other senseless. We'll try to make it upstairs before we go at it like bunnies.
