I have always had a soft spot for Rob Reiners "The Sure thing" with John Cusack and Daphne Zuniga, it is full of wonderful one liners... like
They are hitching, and stuck in the middle of NOwhere and it is pouring with rain, Cusack is trying (unsucessfully) to break into a place for them to get shelter, Zuniga searches her stuff and says, " I have a credit card" he says " wrong kind of lock to open with a credit card"
She says "Yu dont understand, I have a credit card, but I promised my dad I would only use it in an emergency" (this next line convinced me Irony may not be dead in the USA) He says "Maybe one will come up"
