Russell Brand Attacks Robot Geoff on 'Late Late' (VIDEO)

A robot by the name of Geoff is Craig Ferguson's late-night sidekick. Most guests of 'The Late Late Show' (weeknights, 12:37AM ET on CBS) find him pleasant, perhaps funny -- if they have an opinion about the straight-man -robot at all.

Not Russell Brand. He demanded that Geoff keep quiet, poured water all over the robot and said, "This is between us humans from England and Scotland."

But after the commercial break, Geoff made another saucy comment. Brand then pretended to, uh... violate the robot, and the top half of Geoff's skull flew off. That'll teach him.
