"That's where you're wrong. The Thievius Raccoonus doesn't make great thieves. It takes great thieves to make the Thievius Raccoonus!"
In the end, Carmelita decides to give Sly a ten second head start in exchange for saving her life. Sly just stands around, making it look like he's going to wait until the last second just to be a dick. But on the final second, just as she hesitates, Sly kisses Carmelita and runs off. When Carmelita comes to her senses, she realizes that Sly's handcuffed her to the railing.
The final phase of Clockwerk. Being shot out of the sky by a barrage of missiles and crashing into a volcano (twice!) fails to kill him, so you platform across the wreckage of his death ray, climb onto his back and smash him in the face with your cane to finish him off. Clockwerk gloats all the while, but pieces of his head and face break away as you strike him, until he's finally finished (until the sequel, at any rate).
