You'd think there'd be at least one person on the production meeting who would have said something...
Anything.
Seriously...
They probably did. Probably went something like..
Assistant: Uh, say, doesn't that kind look like-
Direct: Yes, we know. Just don't say anything...
Direct: I know what you're thinking, just plead ignorance if someone brings this up.
Assistant: Yeah, but it's pretty obvious.
Direct: I don't know what you're talking about...and I call you a pervert if I did know what you're talking about. Which I don't.
Assistant: They're all gonna know !
Direct: Yes, but they'll all be too polite or embarrased to bring it up.
Assistant: So that's how this is gonna work...
Direct. Yep. Clever, aren't I ?
