The people in charge of the Simpsons must either be Liberals or Canadians. No wonder the quality of the show is so poor.
And that quote isn't funny, especially since I've even heard non-comedians say it.
I've actually stopped paying attention to the Simpsons cartoons since season 10. Like I said, the cartoon is such a disgrace of what it used to be. It's like they're trying to become the Family Guy now. This episode is just another example of the Simpsons atrocious lack of creativity.
