National Lampoon's Christmas Vacation1989

[Clark is looking at lingerie, as a voluptuous saleswoman approaches]

Mary:
Can I show you something?

Clark:
Oh, I was just smelling - smiling. I was just blouse - browsing.

Mary:
For your wife? For your girlfriend?

Clark:
Uh... huh? What happened? I, uh, heh heh. [Mops his forehead with a pair of panties] Well, I guess it just wouldn't... [Realizes what he'd done and puts the panties back] Oh hee hee, it wouldn't be the Christmas shopping season if the stores were any less hooter than they - HOTTER than they are. Whew. It is warm in here, isn't it?

Mary:
You have your coat on.

Clark:
Yes, oh do I? How'd that happen?

Mary:
Because it's cold out?

Clark:
Yes, Yes, it is a bit nipply out. I mean 'nippy out.' [Laughs] What am I saying, nipple? Ah, there is a nip in the air, though.
