1. Bobby Hill (King of the Hill) = Spinelli (Recess)
In 1997, two new animated shows hit the air: Recess and King of the Hill. One featured tomboyish tough girl, the other featured a doughy, sensitive boy who "just ain't right." Both were voiced by Pamela Adlon, who you may also recognize as "Pamela," from Louie.
2. Cogsworth (Beauty and the Beast) = Ratcliffe (Pocahontas) = Wiggins (Pocahontas) = Major Charles Winchester (M*A*S*H) = Jumba (Lilo and Stitch)
If you need a stuffy asshole, look no further than David Ogden Stiers, who has been playing stuffy assholes since at least the '70s. In retrospect, it shouldn't be much of a surprise that the same man who played the uptight surgeon with a good heart in M*A*S*H also voiced the uptight clock with a good heart in Beauty and the Beast, but how did we miss that Ratcliffe and Wiggins were voiced by the same guy?
3. Henri (An American Tail) = Charles Muntz (Up) = Christopher Plummer
At an age when most of us were watching An American Tail (also known as Fievel to idiot children everywhere) we didn't care at all who the actors behind these characters were. Even if those actors are god damn theatrical treasures like Christopher Plummer. Yes, Captain Von Trapp himself is also a friendly french pigeon living in the Statue of Liberty. And he's still popping up in surprising places: as the villainous explorer Charles Muntz in Pixar's Up and as the greybeard Arngeir in Skyrim.
4. Ariel (The Little Mermaid) = All the Barbies (Toy Story trilogy)
If you've ever wondered what Ariel (Jodi Benson) has been up to these days, you might be excited to learn that she's still available if you need to voice a character with an impossibly thin waist.
5. Chef Louis (The Little Mermaid) = Mannfred (Archer) = Odo (Deep Space Nine)
And while we're on the topic of The Little Mermaid, you may be wondering whatever happened to Chef Louis, if you're the kind of person to care about minor, inconsequential characters. That same voice actor also apears in the first season of Archer as the German spy Mannfred. And that voice actor? Rene Auberjonois, perhaps best known for playing Odo in Stark Trek: Deep Space Nine.
6. Shredder (Teenage Mutant Ninja Turtles) = Uncle Phil (The Fresh Prince of Bel-Air)
Teenagers, right? Seems like they're always getting into getting into trouble. Whether it's "one little fight" in West Philadelphia or a never-ending series of battles against mutants. Regardless of the specifics, you can count James Avery to get them in line as the voice of both Shredder and Uncle Phil. "But wait," you might say, "It's a pretty big stretch to say that Shredder helped the turtles in any way." And you're right. Lucky for you Avery ALSO voiced Splinter.
7. Mulan (Mulan) = Finn's Mom (Adventure Time) = Melinda May (Marvel's Agenst of S.H.I.E.L.D)
Mulan, arguable the kick-assiest Disney princess, is also voiced by a pretty kick-ass actress, who seems to be everywhere nerds are. Ming-Na Wen has one foot in comic book world, playing Melinda May in Marvel's Agents of S.H.I.E.L.D, and a foot in the video game world starring in in Final Fantasy: The Spirits Within and in Street Fighter (as Ol' "Hey Stop Kicking So Much" Chun-Li). But, hey, maybe you're one of those people who don't really like video game movies (also known as "normal people"), you might still be pleased to realize that she also voiced Finn's mom (or, at least alternate reality mom) on Adventure Time.
8. Gadget (Chip 'n' Dale Rescue Rangers) = Dot (The Animaniacs) = Agnes Skinner, Dolph, and Jimbo (The Simpsons)
Tress MacNeill's voice is so ubiquitous it tends to pass by unnoticed. A mainstay on The Simpsons, voicing Agnes Skinner, Dolph, Jimbo Jones, and many others. She's voiced dozens of characters in Futurama, Dot in The Animaniacs, Gadget AND Chip in Chip 'n' Dale Rescue Rangers, Angelica's mom on Rugrats, Babs Bunny on Tiny Toon Adventures, and a million other things. You can probably hear her voice in your head more clearly than you can your best friend's.
