A funny dad birthday card works when it's about your dad and nobody else's. Every dad on earth gets "you're old." Only yours sets the thermostat to 68 and checks it twice a day, or has told the story about the moose for the eleventh time. Write the joke about the moose.
Here are 20 lines sorted by the kind of dad, then a card where Dad's real face does the singing.
20 funny lines to write in a birthday card for Dad
The thermostat dad
- Happy birthday to the man who can feel a one-degree change from the garage.
- I'd get you a gift, but you'd say it costs too much and return it.
The dad joke dad
- Happy birthday, Dad. I'd tell you a joke, but you've already told all of them. Twice.
- You're not old. You're a classic. Like your jokes, which were also funny the first forty times.
- Thanks for teaching me that "Hi hungry, I'm Dad" never stops being funny to you.
The grill dad
- Happy birthday to the man who stands next to the grill like he's guarding a national secret.
- Another year older and still no one is allowed to touch the tongs.
- Happy birthday. The burgers were a little dry last time, but we'd never say that to your face. Until now.
The dad who's getting older
- Happy birthday. Your knees now make the same noise as the garage door.
- You still look great. From a distance. With the lights off.
- Happy birthday to the only man who reads the manual before assembling anything. Then ignores it.
The handy (or not handy) dad
- Happy birthday to the man with three hammers and zero finished projects.
- You taught me to fix anything with duct tape. The car still has some on it.
From the daughter
- Happy birthday, Dad. Thanks for checking every boyfriend's handshake like a background check.
- I'm your favorite child. You don't have to say it. The card says it for you.
- You taught me to drive, and you only gripped the door handle a little.
From the son
- Happy birthday, Dad. I'm turning into you, and I've made peace with it. Mostly.
- Thanks for teaching me how to change a tire, how to grill, and how to pretend I know what's wrong with a car.
From the dog (for the dog dad)
- Happy birthday, Dad. I ate your sock. It was a gift. You're welcome.
- Happy birthday to the man who says "he's not allowed on the couch" while we're both on the couch.
End with one real sentence. "Love you, Dad" after a roast lands harder than a whole card of nice. Our birthday roast jokes post has more, sorted by age.
A dad birthday card where Dad sings
On Tangy Limes, you upload a photo of Dad, his face is found and cut out, and it goes on a dancer in a short birthday music video. His mouth opens and closes with an original song. The face is a real photo cutout with no AI changes, so the mustache, the sunburn and the squint all make it in. That's the joke.
Match the card to the dad:
- You're Old Now is the roast card. Dad in a cardigan at the bingo hall, on a porch rocking chair, in a golf cart, then at a cake with too many candles. One face, his. The headline says YOU'RE OLD.
- Birthday Polka starts in a Bavarian beer hall with a brass band, goes to an alpine meadow, and ends in a bowling alley for no reason. For the dad who has opinions about beer.
- Big Band Birthday puts him in a zoot suit in a grand ballroom, then on a train platform with steam. For the dad who still says "they don't make music like this anymore."
- Boot Scootin' Birthday is a western saloon, a rodeo and a barn dance. For the dad who owns a cowboy hat and has never been near a horse.
- Pawty Animals fits two people and two pets. Dogs in your photos are found and put on dancing animals, which is the right card for the dog dad.
Polka, Big Band and Boot Scootin' fit two faces, so you can dance next to him. Pick the card, add a photo where Dad's facing the camera (mouth visible, ideally mid-laugh), and type one of the lines above into the big headline. You can try You're Old Now first, since it does half the roasting for you, or see every option on the birthday cards page.
Sending it to Dad
The preview with his face is free. Keeping the card is $1.99, with no subscription, so you aren't signing up for anything to send one card. Download the MP4, or make a share link that plays right in the text thread. Dad doesn't install anything or sign in. He taps it and watches himself polka.
Send it to the family group chat too. Somebody will put it on the TV at dinner, and he'll pretend to hate it.
