If they were just a little closer in age, it might be hard to tell sandy-haired actors Sean William Scott and David DeLuise apart.

Sean William Scott, 36, made us love to hate him in the teen gross-out comedy series 'American Pie' before getting stuck in the genre with films like 'Dude, Where's My Car?' and 'Road Trip.' Most recently he's moved on to more adult comedies, starring in the remake of 'The Dukes of Hazzard' and 'Role Models.' However, he did make a return to his roots for 'American Reunion' -- because dude, he's Stifler.

Despite appearances, 41-year-old David DeLuise is not an older Sean William Scott (but he IS the son of legendary late comedic actor Dom DeLuise). You probably know him best as Selena Gomez's dad in 'The Wizards of Waverly Place,' on which they often got into wacky magical adventures. He also directed some episodes of the series, and has appeared in guest roles on other shows like 'The Mentalist' and 'Grey's Anatomy.'
