Hieronymus Bosch
Zooey Deschanel (des-channel? dez-shanel? Zoo-ee? Zow-ee? Aw, screw it.)
Any others?
M. Night Shyamalan
I know his last name is pronounced “Shaw-muh-lawn.” But when I see it in print I mentally pronounce it “Shuh-MAY-lee-un.”
Zo-ee Desha-nell.
For me it’s always Dick Cheney. I thought I pronounced it right but Chris Matthews would disagree.
Zzbrigniew Zzenzzinski or whatever the hell it is. Or Amedinejad from Iran. How the hell do you pronounce that, anyway? Ah-med-E-nu-hawd?
On Boston Legal, Denny Crane pronounced it “Ameena-douchebag.”
Given that Crane was a highly educated, immensely successful lawyer, I figured he must have known what he was talking about, so I’ve adopted that pronunciation myself. 
The Iranian president, as I learned from Whoopi Goldberg on The View, sounds like “ahm a dinner jacket.” I giggle a bit every time I hear his name now, but that’s basically how it sounds.
Janeane Garofalo (is she famous?)
Jane - aine?
Jan - een?
Garoh - faloh?
Garaff - aylow?
Goethe.
I think it’s pronounced ‘GER-ta’ but that never springs to mind when I see the name; and when I hear it, it takes me a little while to figure out what the hell they’re talking about.
Not that I know shit about him in the first place.
Ryan Phillipe. Because he’s such an idiot he doesn’t know how to pronounce his own name.
Half the cast of Heroes: Hayden Panettiere, Sendhil Ramamurthy, Milo Ventimiglia.
Tom Smith.
That one actor. He’s been in…movies I guess. I don’t know. Chewbacca Elephant or something.
My humanities teacher pronounced it “Gee-et-ah”. (hard G at the beginning)
Everyone named Nguyen.
I assume that’s the guy I came in to mention: Chiwitel Ejiofor. I’d pay money to watch him read the phonebook but have no idea which syllables to stress in his name.
Hayden Panettiere = Hayden Pantyliner! (I didn’t make it up but have read this creative substitution on other boards)
He’s wrong. The pronunciation of “GER-ta” is correct.
I think the surname Ng is harder – e.g., Maya Soetoro-Ng (Barack Obama’s half sister).
Yes, English “er”, preferably without the “r” pronounced, is about as close as you can get in English to the German o umlaut.
Huh, I never knew that. Wonder why the y’s there then?
This site is really useful for the pronunciation of famous people’s names.
T. J. Houshmandzadeh
Guy Lafleur
Wilmer Valderrama
Brett Favre
