My wife and I both love GF and tend to incorporate some of the lines into our conversation.

Some examples off the top of my head...

"They might," delivered with Tom Hagen inflection, when discussing possibilities.

"That is a complete falsehood" when disagreeing about a fact.

When my wife was pregnant and had strange food requests, she would justify by channelling Enzo. "For da nipper. For da nipper."

I've often thought of trying to end arguments by slashing my arms and yelling "OVER!" but I don't think she'd find that so amusing.
