Few are immune from feeling envy.
Some, though, just can't help expressing it.
In our socially networked world, there are several choices of medium on which to vent one's inadequacies, but none seems so immediate as Twitter.
You can go there and post all sorts of deeply offensive things and actually direct them at the famous people who have turned you green in more places than merely your gills.
For example: "I just saw @JessicaAlba. If this was 2007, I'd be really excited."
Then there's: "Hey @ZachBraff, I could take a picture of a piece of s*** in my toilet and it would be a better movie than Garden State."
Social philanthropist Jimmy Kimmel decided to personalize this phenomenon by getting the celebrity objects of such tweets to appear on camera and read them.
In Friday's fourth edition of "Celebrities Read Mean Tweets," Alba and Braff offered pleasing readings of the above tweets.
Among those also performing were Kate Mara, Kelly Ripa, Brad Paisley ("F*** @BradPaisley and his f***ing country singing f***ing face"), Andy Samberg, No Doubt, Russell Brand, Kid Rock, and Jessica Simpson.
But perhaps the most picturesque reading came from Elizabeth Moss -- Peggy in "Mad Men."
In response to "I can't figure out if Elizabeth Moss is attractive or not," Moss decided to offer the tweeter a little digital assistance.
Perhaps in merely acknowledging that such tweets (and people) exist, these stars are giving them too much respect.
Some might say that part of being a well-paid celebrity involves being able to endure mindless critique.
But there's something more than a little human in seeing the real target of spite reading trollish tweets out loud.
Mind you, it's not as if any of them actually read these things when they were tweeted, is it?
Their people do that, don't they?
