Well, thanks for all these great submissions! 
It was sooo hard to decide, esp. between

CarlPowers:
Lestrade:   Shame they can't carry a tune.     John:  At least they're trying.

jenosborn:
Molly:   "That present better be for me,  Buster,  or your morgue privileges are CUT OFF!"
John (in background):    "You go, Molly."

tobe:
"Oh, Sherlock, you were meant to keep those earlobe collection from the morgue. I dont want it back."



But the winner is, and for sure you will agree on that:

Susi:
Sherlock: "Thank you so much, Molly, but red pants is actually John's colour."

Applause!  You are next! 

Yeah - Red Pants Saturday! Congrats, Susi!
