Turning 40 is a monumental occasion. It's the age where you're wise enough to know better, but still young enough to do it anyway. It's a decade of peak confidence, questionable dance moves at weddings, and realizing that a good night's sleep is the most luxurious gift of all. While a heartfelt message is always lovely, a 40th birthday practically begs for a good-natured laugh.

If your friend, partner, or family member is hitting the big 4-0, it's your sacred duty to welcome them to the club with a bit of humor. Forget the generic "Happy Birthday" and choose a message that will make them laugh so hard they spill their sensible, age-appropriate beverage. We’ve curated the perfect list of funny wishes for every kind of 40-year-old in your life.

  • Forty isn’t old if you’re a tree. Or a bottle of scotch. Or you. Happy Birthday!

Mention a specific memory, an inside joke, or just a simple, "Love you, you old fart!" Your friend will appreciate the thought and, more importantly, the laugh you gave them on their special day.
