Well y’know, that’s why Merv Griffin hired Vanna White — her head is too big for her body. Apparently big-headed people are thought to “read well” on TV.
And yes, that is the only qualification to be a TV “journalist.
This is attributed to a person using the name "Cervantes" commenting on a blog here. (This blog also refers to Tony Snow and Brit Hume as examples of the big head phenomenon, and along with some crude language and general meanness, uses the term megacephalic, which may be useful going forward.) For those who don't think a single, anonymous blog comment qualifies as solid sourcing (what's the weather like back there in 2003?) I have something even better:
Overheard on the recent E! True Hollywood Story, Vanna White: Merv Griffin believes that people with slightly larger heads tend to be more successful. The game show creator says it was one reason he originally chose Vanna over a smaller-headed letter-turning competitor.
Attribution to E! should be enough for even the most skeptical, so we'll just stamp "fact" on this one.
So now we know - if you want to succeed in TV but you're not an idol, ballroom dancer, castaway or ex-jock, take a good hard look in the mirror as say, "Is my head - and I mean this literally, not figuratively - really big enough?" And after that, better stop talking to yourself in the mirror, that might be misinterpreted.
