Sid Caesar reborn

"Back in the old days, Sid Caesar, for those of you old enough to remember, was called a comic genius for impersonating foreign languages that he couldn't speak," Limbaugh said. "But today the left says that was racism; it was bigotry; it was insulting. And it wasn't. It was a service."

The left didn't say it Rush.  The Chinese Americans said it. 
What is "a service"? What possible service can you be doing?

I used to watch Sid Caesar too Rush.  You aren't any Sid Caesar.
