*shrug* 'Bil Cosby' is close enough. I doubt anyone would say "Bill cosby" without knowing it was actually Bill Cosby in The Simpsons. No sense in being anal etc.

I'm sure Bill Cosby wouldn't appreciate being credited with that quote, I'm also sure the people who wrote that joke would appreciate Bill Cosby getting credit for it.

Its not being anal, its being correct. If you wanna see me be anal maybe you can come over later tonight and I can help loosen you up.
