Let's make this birthday one to remember.

64 years old (Born on December 09, 1960)

Happy birthday, Jeff "Swampy" Marsh! The man who made summer vacations endless and roller coasters in backyards believable— it's no wonder you're celebrated by countless fans (and perhaps some confused platypuses). Three Emmy nods couldn't even fully capture your hilarious genius or the epic scale of Doofenshmirtz' evil-yet-loveable failures. Thanks for gifting us all with Phineas and Ferb's wacky adventures since 2007.

Here's to a timeless mastermind whose humor still resonates today: may your creative ideas always outnumber Perry’s secret identities, may Candace never actually bust you, and let this year bring new unforgettable exploits simpler than inventing teleportation just to grab snacks from across the room. Happy birthday Swampy—you rock!
