Serj Tankian. What a character.
My top picks are Meryl Streep, Betty white, Sigourney Weaver, and of course anyone from Pixar.
Probably Ellen Degeneres or Micheal Cera.
Ellen because she’s awesome and she’s the voice of Dory.
Micheal Cera cuz it seems like he’d be cool to hang out with.
Peter Cullen, Lee Unkrich, Frank Welker, Garry Chalk, David Kaye, and John Lasseter, Corey Burton, and Jim Cummings are the tops on the list.
Lasseter and Unkrich directed Toy Story, Toy Story 2, and Toy Story 3 in that order, and gave me the greatest films of all time.
Peter Cullen voiced has voiced three incarnations of Optimus Prime - the original '80’s series “G1”, the live-action films, and the upcoming Transformers: Prime series.
Frank Welker, in addition to voicing Scooby-Doo, Dr. Claw, and countless extras in films, has voiced the original Megatron, Soundwave, and Ravage in the G1 Transformers series. He reprised the roles of Soundwave and Ravage in the live-action films, and voiced Devastator and others in the film. He returns as Megatron for the Prime series.
Garry Chalk voiced Optimus Primal, Prime’s descendent, in Beast Wars, and then its’ sequel series Beast Machines.
David Kaye voiced Megatron in the Beast series, and returned to Megatron in the Armada, Energon, and Cybertron anime series in the early 2000’s. In 2007, he returned as a Transformers series regular - but this time, as OPTIMUS PRIME. He also voiced several other characters: Lugnut, Grimlock, Warpath, Highbrow, and Sparkplug Witwicky.
Corey Burton has voiced countless people in movies and TV. Some roles include Count Dooku from Star Wars, many Disney characters, and Shockwave from the G1 Transformers series. He came to Transformers Animated in 2007 as Ratchet, Megatron, Longarm, Spike Witwicky, and Shockwave.
Jim Cummings has always been Disney’s boy, and has voiced Pooh, Tigger, and Pete. His gravelly voice is AWESOME.
Others I’d want to meet: Bud Luckey, Bumper Robinson, Tom Kenny, Jess Harnell, Bill Fagerbakke, R. Lee Ermey, Tim Allen, Wallace Shawn, Blake Clark, Don Rickles, Estelle Harris, John Ratzenburger, Jeff Garlin, and John Goodman.
In terms of HAWT female celebrities I’d like to meet… don’t judge me… Kim Kardashian, Fergie, and Victoria Justice.
EDIT: After seeing a recent episode of Law and Order: SVU, MIchelle Borth too for sheer HAWTNESS.
Chopperface, your Pixar Planet username made my day. 
Dinobot!!!
I thought about using Rhinox, as he was my other favorite character from Beast Wars, but “a deed once done cannot be undone!” xD
“What kind of a name is “pixel caaandy?” You’re basically ringing Tarantulas’ dinner bell! You’re worse than when the VERMIN named himself!!!”
xD How I wish I had Scott McNeil’s voice talent. 
I met and befriend one celebrity I wanted to meet. Not Mr. Lasseter or Sid Meier though.
Chopperface - It’s like a mishmash between my old internet alias (Candy) and a word that sounded like Pixar. hehe. 
Ah. I wasn’t trying to criticize you, I just typed what Dinobot would probably say. Sorry if I made it look like that.
Oh, I figured that with the sentences that came after, but I guess I’m just blonde. LOL it’s okay. My bad.
