* The entire opening with Holmes and Watson, but especially the first bit:
-->'''Holmes:''' (via a handwritten sign) "Ugly 6'3" murderer at keyhole."
-->'''Watson:''' "Holy Jesus Christ!"
-->'''Holmes:''' (via another sign) "Act normally."
-->'''Watson:''' "...but it's cold outside!"
* Sacker has been holding a cup, and seems to be proffering it to Sigurson, who takes it and sips.
-->'''Sigurson:''' You call this tea?
-->'''Sacker:''' No sir. I call it hot water. I was merely rinsing out the cup when you grabbed it.
* The entore opera sequence.
-->'''Henchman:''' Why don't we all drink some-
-->'''Gambetti:''' (throws prop at him) SHUT YOUR MOUTH!
* The entire auction scene, especially when the otherwise dimwitted minion Finney (Roy Kinnear) has to help Math Professor Moriarty (Leo Mc Kern) use long division with decimals:
-->'''Moriarty:''' Oh Christ, how do you do this?
-->'''Finney:''' Well, you put down 11.18...
-->'''Moriarty:''' Oh sure, I wouldn't know even to put down 11.18.., What I'm askin' ya idiot, is whether you multiply or divide?
-->'''Finney:''' Divide.
-->'''Moriarty:''' Are you sure?
-->'''Finney:''' Yeah.
-->'''Moriarty:''' I'll kill you if you screw this up.
