What a great idea for a thread, Juan! Sorry I can't think of anything right off, but I'll return if I do.

Loftan just offered:

"Here's lookin' at you, kid" from Casablanca and "You had me at hello," from Jerry McGuire--and I have no idea what Lof's talking about, but she assures me this is a phrase that her age group picked up.

Edit:

Lof's got another one--

"I don't think we're in Kansas anymore" from Oz
