Let's make this birthday one to remember.

27 years old (Born on July 14, 1997)

Happy Birthday, Zac Mann! From your hilarious Vine antics to serenading us with "Sunshine," you've kept our feeds brighter and funnier than ever. Whether you're hitting those high notes or making everyday moments ridiculously entertaining, you always manage to put a smile on everyone's face.

Here's hoping this year brings even more catchy tunes and laugh-out-loud videos—because let's be honest, nobody does daily life vlogs quite like you do. Keep shining bright (pun totally intended), keep the laughs coming strong, and remember: age is just a number...but funny Vines are forever timeless! Cheers to another amazing trip around the sun!
