Let's make this birthday one to remember.

46 years old (Born on March 14, 1979)

Happy birthday, Chris Klein! Here's to the guy who taught us how awkwardly awesome high school romance could truly be. Your role as Oz Ostreicher in "American Pie" still makes us laugh—and cringe—in all the right ways.

Over two decades later and your charm hasn't aged one bit—just like Stifler's jokes never get old (well, almost). Cheers on another year filled with memorable moments, laughter that rivals Jim’s embarrassing pie scene, and success sweeter than Finch finally winning over Stifler's mom. Have an unforgettable day that's worthy of a classic Hollywood slow-mo walk through prom night!
