Happy Birthday, John Stamos! From rocking the leather jacket as Uncle Jesse on "Full House" to charming us all with your timeless hair and ageless charisma, you've truly mastered the art of staying effortlessly cool. Seriously—do you have a secret fountain of youth hidden somewhere?Whether you're jamming out on stage or making us laugh in recent projects like "Big Shot," your talent continues to shine brighter than Uncle Jesse's perfectly styled mullet ever did. Here's hoping this birthday is filled with good music, great laughs, and absolutely zero bad hair days. Have mercy—and celebrate big!
