Rob Paulson is an actor who is currently known primarily for two things, the Mr. Opportunity series of television and radio ads for Honda and "Yakko's World".
"Yakko's World" is an amazing collaboration between the writer, Randy Rogel, director, Rusty Mills, and the performer, Rob Paulson. The second episode of "Animaniacs" begins with a globe of the world and an announcer stating, "And now, the nations of the world, brought to you by Yakko Warner!"
As phenomenal as that feat was, even more amazing are the times Paulson has performed the same feat in public, unrehearsed and without a script! You can see this version from Comic-Con 2006
and you can go here for another version.
