Sure, we've all probably done Yoda, or Jar Jar, or even Harrison Ford. But to nail all those AND perfectly get Hayden Christensen's weird, disinterested Brooklyn-meets-Canada twang? Or perfectly land Ewan McGregor's imperfect Alec Guinness? Vocally mimic the Probe Droid's audio code? And then, as a bonus, embody Matthew McConaughey rambling on about the new sequels?
These guys are impressive. And the way the Jar Jar bit ends should please everyone.
