Ok, I missed yesterday, so...

 Colonel Mustard: Wadsworth, am I right in thinking there is no body else in this house?
Wadsworth: Ummm, no.
Colonel Mustard: Then there is someone else in this house?
Wadsworth: No, sorry. I said no meaning yes.
Colonel Mustard: No meaning yes? Look I want a straight answer, is there someone else, or isn't there? Yes or no?
Wadsworth: Ummm, no.
Colonel Mustard: No there is, or no there isn't?
Wadsworth: Yes.
Colonel Mustard: Well, there is still some confusion as to whether or not there is anybody else in this house.
Wadsworth: I told you there isn't!
Colonel Mustard: There isn't any confusion, or there isn't anybody else?
Wadsworth: Either, or both!
Colonel Mustard: Just give me a clear answer!
Wadsworth: Certainly!
[clears his throat]
Wadsworth: What was the question?
Colonel Mustard: Is there anybody else in the house!
All: NO!!!

-Clue

Yes, it is a movie!
