Art imitates life imitates art
Actually, Dr. Crane's real-life counterpart Kelsey Grammer is the one having some nitpicky fun. The actor created a Twitter account, promising followers he had done so in order to help them stop making idiots of themselves by way of poor online grammar.
So far, Grammer's corrections have been gently chiding, a far cry from his classic character on the eponymous show, who would have reveled in one-upping the Twittersphere. All I know is that if there were ever a way to convince my Frasier-loving, English-teaching mom to join Twitter, it just appeared in the form of #KelseyGrammerGrammar. --Sarah Eberspacher
