Let's make this birthday one to remember.

56 years old (Born on September 27, 1968)

Happy Birthday, Patrick Muldoon! From charming us as Jeff Hunter in "Saved by the Bell," to stirring up drama on "Melrose Place" and bravely battling giant alien bugs in "Starship Troopers," you've truly done it all. Your ability to seamlessly shift from teen heartthrob antics at Bayside High into intergalactic heroics proves you're timelessly versatile—and forever young!

Here's hoping your birthday is filled with fewer bug invasions than Klendathu but just as much excitement and adventure. May this year bring you even more memorable roles, laughter-filled moments, and perhaps a reunion or two—because nostalgia never goes out of style!
