Gerry Bamman as Uncle Frank
Uncle Frank is Kevin's uncle and the father of Tracy, Rod, Sondra, Brooke, and Fuller McCallister. He relocated his entire family from Ohio to his brother Peter's house the day before their trip to Paris. The evening before their grand trip, a heated argument between Kevin and Buzz erupted at dinner, prompting Uncle Frank to call his nephew a "little jerk." Not exactly the ideal uncle.
Frank isn't exactly the kind of guy anyone would wish for as an uncle. For starters, he shamelessly gives away the shrimp that Kevin's sister-in-law was saving for dinner to his children. In a deleted scene, he even pranks Kevin by falsely telling him his name in French would be "Yank" before pulling a prank on him.
