"Dodos don’t talk," Fred Flintstone says in The Flintstones episode "The Buffalo Convention."

"This one can," the sleazy salesman on the street insists. He lifts a cloth off a birdcage to reveal a pinkish purple dodo, looking quite defeated.

Fred buys the bird for $5 as a birthday present for Wilma, but really, the dodo bird was a gift for Flintstones fans. For years, fans have found themselves quoting this colorful character called Doozy.

"Doozy wanna cracker, Doozy wanna cracker," the dodo repeats after Barney at one point, following a moment when Barney and Fred have hatched a scheme to silence the bird from revealing a secret by stuffing its mouth full of salty crackers.

"Frantic City!" the bird squawks at another point, leading the boys' wives to catch them in the act of deception.

Throughout the episode, Doozy continues to snitch on Fred and Barney to Wilma and Betty, and the joke helped make the otherwise fleeting character stick in the memory of fans.

It may interest you to know that Doozy the dodo was hatched in the brain of a writer who is partially responsible for one of the silliest bird-based earworms in cartoon history.

Warren Foster is the funny writer behind "The Buffalo Convention." He got his start in the 1930s writing Porky Pig cartoons. After a decade writing for Looney Tunes, Foster got together with TV legend Alan Livingston and co-wrote Tweety's theme song "I Tawt I Taw a Puddy Tat" in 1950, along with composer Billy May (who later wrote the Green Acres theme).

"I am a widdle tiny bird / My name is Tweety Pie," Tweety sings. "I wiv inside my birdcage / A-hangin' way up high."

This cartoon theme song repeats Tweety's catchphrase, including bursting out to insist, "I did, I taw a puddy tat!"

And then Sylvester the cat takes over, repeating his own catchphrase, "Sufferin' succotash," in a delightful, sing-songy way.

Tweety had been featured in Looney Tunes cartoons since 1942, so it took a pretty long time before we got this theme song. It didn’t matter how long it took to real Tweety fans, who can absolutely sing every word. Next time you hear it, though, you'll know Tweety's catchy theme came from the same guy who gave Wilma Flintstone that iconic talking dodo.

But it's far likelier that Doozy reminds you of a different iconic cartoon bird that also hatched from Foster's funny mind.

Foster and animator/illustrator Robert McKimson teamed up and created Foghorn Leghorn in 1946. The rooster known for running his mouth in a thick country drawl was definitely a character who introduced zany cartoon tension like Doozy did, whereas Tweety was different, and really just a sweetie pie. (Most people don’t realize that Foghorn Leghorn was a spoof of another fictional character, Senator Claghorn, who appeared on Fred Allen's radio show in the 1940s.)

"We gotta ditch this gabby bird," Fred says at one point in "The Buffalo Convention."

Doozy only appears in this one episode of The Flintstones, so clearly Hanna-Barbera agreed with Fred. But we bet you remember Doozy.
