Let's make this birthday one to remember.

55 years old (Born on October 01, 1969)

Happy Birthday, Zach Galifianakis! May your day be filled with more laughs than Alan Garner's unforgettable rooftop toast in "The Hangover." Your comedic genius has given us countless hilarious moments—from awkwardly interviewing celebrities on "Between Two Ferns" to carrying around a baby named Carlos through Vegas chaos. You've truly mastered the art of making absurdity look effortlessly cool.

Here's hoping this birthday brings you fewer tigers and missing teeth but just as many memorable adventures. Keep being brilliantly weird—because nobody rocks a satchel quite like you do. Cheers to another year of laughter, success, and questionable life choices!
