Arby's - Monkey Dance
Summary: Scientists observe monkeys dancing in an office environment, but are more amazed by the Arby's in front of them.
Scientists are undergoing a study of chimpanzees in a simulated work environment, and one of the monkeys switches a radio station from classical to Irish music. The monkeys all start to do an Irish step-dance typical of the Riverdance theatrical show.
The scientists are amazed, but it turns out what they're fascinated with are the Arby's in front of them. Variations of the ad have the product being Ultimate BLT and Chicken Salad Sandwich with Pecan, and another version with Toasted Subs.
