In The Pursuit of Happyness, after Chris gets the internship at Dean Witter and just before he goes to the football game with Mr. Ribbon, it shows a list that Chris is using to make cold calls. He states that they're "working up the list", however, out of what seems to be impatience, Chris jumps to the top of the list and calls Mr. Walter Ribbon, Pension Fund CEO.
As Chris scrolls up the list to circle Mr. Ribbon's name, he briefly looks around in a somewhat secretive manner -- would Chris have gotten in trouble if his actions were discovered by Dean Witter?
And then.. given what seems to be the fact that these firms maintain close relationships with each other, wouldn't word have gotten back to Dean Witter, saying that an intern-in-training is calling/hassling a CEO with a cliché sales pitch?
