"My son is furthering his education"
or how about
"that's a mighty big tree griswold, where do you plan on putting it?"
"why don't you bend over and I'll show you"
"HEY..you got a lot of nerve talking to me like that Griswold"
"oooo I wasn't talking to YOU"
"wouldn't be the holidays if it wasn't any hooter..HOTTER in the stores"
I could quote that movie all day long.
