"I know what you're thinking. Did he fire six shots or only five? Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being as this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question: Do I feel lucky? Well, do ya punk?"
- Clint Eastwood as Harry Callahan (Dirty Harry, 1971)
Of course, you could go with the shortened version, "Well, do ya punk?"
I am not really sure how that will go over with your fellow employees, but I think it would be funny.
Another is: "Go ahead, make my day!"
