Whoa... reminds me of this one Twilight Zone episode that was on recently with one of the guys from American Pie. He pays attention to a bum when everyone else is ignoring him, and ends up sort of arguing with him about what to give him, and then just gives him everything and walks away. Bum ends up giving him a voice recorder that can go forward and backward in time. He's a gambler, so this changes everything for him...
