Funny Things to Write in a Birthday Card

Looking for the perfect blend of humor and heart? These messages range from silly to clever, suitable for everyone from your bestie to your boss. Each one comes with suggestions on exactly when and how to use it for maximum impact.

1. “Inside this card is my gift to you: my amazing sense of humor. You’re welcome.”

Perfect for close friends who appreciate your wit, this message sets a playful tone right from the start. The mock self-importance makes it even funnier, especially when paired with a small or silly actual gift.

2. “Congratulations on being slightly closer to getting senior citizen discounts!”

This message works brilliantly for middle-aged friends and family members who don’t mind joking about aging. The key is knowing your audience – save this one for people who regularly crack age jokes themselves.

Plus, who doesn’t love saving money? This message reminds them that aging has its perks, like cheaper movie tickets and early-bird specials at their favorite restaurants.
