Scarface i think, only ever seen that movie once, wasn't that fond of it.

"My mother thanks you. My father thanks you. My sister thanks you. And I thank you."

This one is quite an old movie, i'll be quit impressed if anyone else has actually seen this.

Yankee Doodle Dandy. Ma used o watch it back in the day.

"C'mon man, we're all rock and rollers here"

"Hey little girl thanks for the help, here you can have this back."
"Keep it I got a pitbull now."

I'll be amazed if anyone gets this one it's a very obscure referance

That would be The Sum of All Fears, thats the only Clancy movie I've actually seen.

Since I recently bought a new movie I'll use a quote from that:

1st Person: "We go back to our homeroom for dismissal. Unless you have a pass for sports or something. "
2nd Person: "Is that what you did on the day in question?"
1st PersoN: "No. Mr. Gettys asked me to stay after class."

EDIT: BAH! I was on the first page.
That film is Back To The Future. That is not a very obsecure reference ;P Not for me, anyway. I loved Back to the Future

To be more accurate, that is from part 2, when Marty gives the hoverboard back to the little girl and the girl had stolen the better hoverboard, right?

Ok how about this:
"This means something. This is important."
Here's a hint it's said about a plate of mash potatoes.
