Where is this simpsons quote from?

Mr Burns: And remember, you must get the jade monkey by the next full moon!
Smithers: But Sir, we found the Jade Monkey. It was in your other pants.
Mr Burns: Excellent…

A friend of mine used to say this all the time. I was wondering which episode it’s from? Oh, and I’m quoting a quote, so I doubt it’s 100 accurate.

According to snpp.com, it’s from “Homer Goes to College”.

Hope this helps.

Oh, and the complete exchange is

I could be wrong, but I think it’s from The Simpsons.

[sub]Come on. SOMEONE had to say it.[/sub]

OK then, but does this “jade monkey” bit in The Simpsons refer to a famous detective novel/movie? If so, which one?

The Simpson’s Archive breifly mentions the jade monkey stuff has some reference to The Maltese Falcon. Don’t ask me where or what or if that’s even right though.
