100 Funny Things to Write in a Birthday Card

Birthday cards deserve better than “Wishing you a wonderful day!” These 100 funny things to write cover every relationship — best friends, partners, parents, siblings, coworkers, and everyone else — with messages that range from affectionately sarcastic to gently existential to outright absurd. Use them exactly or as inspiration. The goal is a message they actually remember.

For Your Best Friend

Your best friend relationship earns you the most latitude. Use it.

1. “Another year older. Another year of me still being the better-looking one of us.”
2. “Happy birthday! I was going to get you something nice, but then I remembered you still owe me from 2019.”
3. “You’re not getting older. You’re getting more distinguished. Like a cheese. Or a wine. Or old furniture.”
4. “Happy birthday to the person who has seen me at my absolute worst and chooses to stay anyway. You’re either incredibly loyal or have very low standards.”
5. “I’d say you don’t look a day over [age], but I believe in honesty in friendship.”
6. “Thank you for another year of being the reason I have so many good stories.”
7. “Happy birthday! You’re officially old enough that our conversations are starting to involve doctors we like.”
8. “I got you this card because I love you. I did not get you anything else because I also love myself.”
9. “On your birthday, I want you to know: I have never once regretted knowing you. Except that one time. You know which time.”
10. “Happy birthday! May today be the day things start going suspiciously well for no clear reason.”
11. “You’re one of the few people I would actually help move. That’s love.”
12. “Age is just a number. A big number. That keeps getting bigger. Every year. Without stopping.”
13. “Here’s to another year of our friendship, which has survived things that should have ended friendships.”
14. “Happy birthday! I hope it’s as good as you pretend you are.”
15. “You’ve made it another year without me needing to explain you to anyone. Mostly.”

For Your Significant Other

Affectionate but with the freedom of someone who knows you extremely well.

16. “Happy birthday, love. I’m so glad I picked you. The other options were much worse.”
17. “Another year older, same amount of annoying. I’ll keep you.”
18. “I got you a card AND I’m pretending the house is clean. You’re welcome.”
19. “Happy birthday to the person who has heard all my stories twice and still laughs.”
20. “You are the reason I believe in love. Also the reason I sometimes question my judgment. Both things.”
21. “I thought about getting you something expensive, and then I thought about what you’d actually want, and the answer is that you’d want me to be nicer to you. So: I’ll try.”
22. “Happy birthday! You are everything I was hoping for and several things I wasn’t expecting.”
23. “Growing old with you is the plan. Growing up with you remains under negotiation.”
24. “I have loved you through a lot of seasons, haircuts, and questionable decisions. Here’s to many more.”
25. “You’ve been mine for [number] years, and I still choose you. Even when you load the dishwasher wrong.”

For a Parent

Appreciative but with enough humor to remind them who raised you.

26. “Happy birthday, Mom/Dad! Everything good about me is your fault.”
27. “Thank you for not selling me when I was a teenager. It must have been tempting.”
28. “Happy birthday! This card cost more than you charged me for everything you’ve ever done for me. I’m still in debt.”
29. “You gave me life and the ability to embarrass myself in public. I use both regularly.”
30. “Happy birthday to the person who knows exactly where I came from and loves me anyway.”
31. “I turned out this way. You have only yourself to blame. Happy birthday!”
32. “Thanks for all the things I didn’t thank you for at the time.”
33. “Happy birthday! I called instead of texting because I knew you’d prefer it. You’re welcome. Love you.”
34. “You always said I could be anything I wanted. I’m still working on it. Thank you for your patience.”
35. “For your birthday, I’m giving you the gift of a phone call where I don’t ask for anything. Enjoy it.”

For a Sibling

The relationship where you can say almost anything.

36. “Happy birthday to my sibling, who I was stuck with and then chose. Different from the other kind.”
37. “I’m only slightly jealous that you exist. Happy birthday.”
38. “You are living proof that our parents had a type. Happy birthday.”
39. “Happy birthday! I’m required by family law to celebrate you today. I’m genuinely doing it willingly though.”
40. “Growing up with you was an experience. I would not trade it. I also would not repeat it.”
41. “You’re my favorite sibling. That you’re also my only sibling is irrelevant.”
42. “Happy birthday! You’ve made it another year without me telling everyone what actually happened in 2011.”
43. “I love you in spite of knowing everything about you. That’s the highest form of love.”
44. “Happy birthday! Here’s to another year of me being the better-looking, more charming, and overall superior sibling. I’m so glad you’re here to witness it.”
45. “Nobody will ever know us the way we know each other. For some of it, I’m grateful.”

For a Coworker or Colleague

Professional enough to be appropriate, human enough to be memorable.

46. “Happy birthday! You’ve survived another year of this. That’s an achievement.”
47. “Wishing you a birthday that’s better than a Monday, which is the best I can offer given our circumstances.”
