If you enjoyed Jared Leto's take on the 'Intense Staredown' segment from 'The Tonight Show' -- okay, it was good, it really was -- you're going to love Robert Downey Jr.'s spin. 'The Judge' star hit the show last night to chat about all kinds of things with host Jimmy Fallon, but the uncontested highlight of his visit was the truly intense stare-off between the two.

In mere minutes, Downey managed to show off his comedic chops with nothing but style (and a hell of a hairdo), with his "thoughts" running the gamut between stuffed crust pizza and the perils of sneezing. Fallon was there, too, but even he couldn't compete with what RDJ was dishing out.
