[Quotes: As God is my witness...]

Maybe. That sounds like it might be right. Which episode is that?

[Quotes: As God is my witness...]

I am looking for the episode or just the exact quote from Johnny Fever. He is on air doing an ad (?) and was talking about chemicals (chemistry?). I loved that quote when I heard it as a kid, but cannot remember it now. Please help me find the episode or exact quote. Thanks in advance.
