Let's make this birthday one to remember.

63 years old (Born on July 14, 1961)

Happy Birthday to the legendary Kyle Gass—master guitarist, comedic genius, and one-half of Tenacious D! Your epic riffs have melted faces worldwide while your hilarious antics alongside Jack Black continue to inspire air guitarists everywhere. From battling Satan himself in "The Pick of Destiny" to rocking stages with unmatched charisma, you've proven that rock 'n' roll can be both badass and brilliantly funny.

Here's hoping this birthday is as timelessly awesome as your unforgettable performances. May you keep shredding guitars (and expectations) for many more years—and remember: you're not getting older; you're just leveling up on awesomeness!
