If you're thinking about auditioning for American Idol or whatever the equivalent show is in England*, I have some important advice.
If you make it to the finals, there will be physical consequences. There's indisputable proof that one of the unfortunate results of shooting to stardom on a nationally televised singing contest is that your head gets bigger. I mean, it swells to the point that your neck alone is simply unable to hold it up.
Visual evidence comes in the form of the covers of the latest CDs by two recent singing sensations. Witness:
(Susan Boyle, from whatever that British show is)
I guess the only good news is that in some cases, singers only need one hand (usually the right) to keep their heads from falling over in all of their pop-star glory.
(Adam Lambert, on a cover that could only have been designed in the early 1980s)
It even applies to the previous generation of Idols.
(Carrie Underwood, going with the palm)
Apparently, Carrie Underwood is one of the fortunate ones, able to provide adequate head support with but a single hand. I assume she had exercises - like maybe taking a Louisville Slugger to both head lights and slashing holes in in all four tires - that helped her avoid the dreaded Boyle two-handed lift.
* I think it's Ye Olde British Idole, but I'm too lazy to look it up.
