Cadbury Schweppes, Dog Walkers
A good-looking young man is walking down a sidewalk sipping a Dr. Pepper. He catches the eyes of many women who stare and smile.
At one point, he walks past a hotel/apartment building, and the doorman does a double-take upon seeing him. The doorman's head looks downward, suggesting that he's taking a look at the man's butt. At this point it's revealed, however, that he's attracting attention not for his looks, but because he's a dog walker, and he's walking several dogs on leashes.
He eventually runs into a female dog walker, also with several dogs in tow and sipping a Dr. Pepper, and they get tangled up together.
