Jimmy Fallon does his best Russell Brand with Russell Brand on Late Night with Jimmy Fallon last night. Awkward, or the best thing ever?

Jimmy's accent is pretty dire, but he does nail the basic humour and delivery of Brand. Worry not though, as Russell gets his own back in a very Russell Brand way.

Brand had alluded to some form of mimicry yesterday after tweeting the following picture with the caption 'Me and @jimmyfallon are becoming one #inagayway'. We assume that's Brand on the right, but then neither head of hair matches. Should we be expecting some more Fallon/Brand collaborations? Who knows.
