Let's make this birthday one to remember.

53 years old (Born on January 12, 1972)

Happy birthday to Randy and Jason Sklar—the funniest identical twins since Danny DeVito and Arnold Schwarzenegger! From cracking us up on "Chelsea Lately" to their unforgettable antics in "It's Always Sunny in Philadelphia," you've proven two Sklars are always better than one. Your stand-up album, 2004's hilarious gem “Poppin' the Hood!”, still pops laughter nearly twenty years later.

Whether you're riffing off each other’s punchlines or confusing audiences with your comedic twin telepathy, you continue bringing double trouble (and twice the laughs) wherever you go. Here's hoping this year brings even more success—and fewer mix-ups at Starbucks orders!
