Bright Yellow Shirt

In advertisement for Capital One credit cards, an employee played by David Spade works in an office in which "No is company policy." But when a customer gets tired of being told "no" one too many times, he declares he's "coming to find you." As it turns out, he somehow found the office right then and there, so Spade's character tricks him into thinking he's another employee wearing a "bright yellow shirt." Cue the most ridiculous girly scream from the unfortunate employee as the angry customer rushes him.
