Let's make this birthday one to remember.

31 years old (Born on September 18, 1993)

Happy Birthday, Patrick Schwarzenegger! From charming us in "The Benchwarmers" to building your own entrepreneurial empire, you've proven that being Arnold's son isn't just about muscles—it's also about flexing those business skills. Your journey from Hollywood sets to savvy investments has been impressive and inspiring.

May this year bring you even more success (and fewer jokes comparing biceps with Dad). Keep making waves both on-screen and off; after all, you're the only person who can say they grew up hearing “I'll be back” as a bedtime story. Here's wishing you laughter-filled days ahead—and remember: birthdays are like workouts—the heavier the cake slice, the better!
