Pepsi is a brand of carbonated beverage with product placement in Home Alone. It was featured in the scene where the McCallister family is eating pizza, take Fuller who was drinking that sort of beverage and his mother Leslie told him to go easy on it, shortly before Buzz started a fight for eating Kevin's cheese pizza on purpose. In the original home video release of Home Alone, a commercial for Pepsi is featured on the tape.
However, at the beginning of Home Alone 2: Lost in New York, Coca-Cola was the main carbonated beverage as seen when Fuller had his can stolen taken from his father, Frank and said, "Hey, Hey! Easy on the fluids pal, the rubber sheets are packed!"
