Rush Limbaugh was stunned when he learned the language

he uses to call Barack Obama's supporters 'savages' and

 'walking human debris' is a descendant of the mother

 tongue of mother tongues, which arose in Africa

50,000 years ago.  He is so upset, in fact, that he

 is said to be considering eschewing language

 altogether, communicating henceforth only by

means of rude noises and gestures.
