Yup, I saw the movie as well and I did it not too long ago to show off for a girl.
I was in my convertible at a red light and some ugly ass bum walked up to the car with a torn and dirty Dunkin Donuts coffee cup. I never keep change in the car since I hate loose stuff so I gave the poor bastard a 50 dollar bill. The girl was impressed and she thought I was nice. Anyway, I'm still waiting for my PAY IT FORWARD to get back to me. Any ideas how long this takes?
