Did This Really Happen?

I'm still wondering if this really happened.
This may not be funny at all. So I apologize now, if it's not.
I'm sitting at my desk at work.
My boss heads over to my other boss' office to get on a conference call.
They are getting things situated and they still had the door open and so I can still hear what is going on inside. Not that I'm listening in on what they are talking about but all of a sudden I hear one of them say in a PERFECT Steve Martin voice,
"All I need is this chair...and...this chair"
Then the other one says,
"This thermos is all I need..."
It was classic. I almost fell off of my chair. It was hilarious.
It might have only been hilarious if you know my bosses, or have heard stories. And maybe if you know what movie this quote came from.
Anyone know it!?
