It's also a moment of awesome for the bad guys. Ace said they couldn't aim at that speed. Then he caught the bullet and went "Hmmmm." It's a silent Shut Up, Kirk! from them, and he doesn't mock them afterward.
For detectives, Ace takes one look at Cadby when asked how good he is and he picks up the following:
Ace: You're an extreme workaholic. You recently returned from a short trip to Gotan in northern Africa. Upon your return, you more than likely took a nasty spill because of some... shoddy masonry work.
Cadby: Very impressive. Might one ask how?
Ace: Surely. (inhales) The abrasion on the palm of your left hand is from a sustained breaking a fall of three- to five-feet, the small plaster on the tip of your shoe pointed to a careless mason being the culprit, your new watch, a quality forgery of a Cartier was most likely purchased through the North African Black Market, known to reside in Gotan. (inhales)
Cadby: And my work habits?
Ace: Yes. A workaholic. The urine stain on your pants would signify that you're a single-shake man, far too busy for the follow-up jiggle.
Here's one for all you animal lovers: The scene where Ace beats up a Monopoly Guy lookalike and uses him as a pelt because he hates the man's wife's fox pelt. Also a Funny Moment.
Do not pass Go! Do not collect two hundred dollars!
Ace was shown the Trophy Room and has the appropriate reaction as an animal lover. He gets back at Cadby as he leaves the manor with the aid of the local elephant.
