* ''[[ComicBook/DisneyDucksComicUniverse The Duck Who Never Was]]'' plays with this. It was first published in 1994 (the sixtith anniversaty of Donald's debut), and yet Donald's age was never stated throughout the comic. In fact, the one character who says Donald is sixty has been reading Donald's filled-in form upside down.

A staple in most classic sitcoms and animated television programs is the "ageless birthday episode." This is an episode that centers on a specific character's birthday but never mentions the character's new age. If this character's actual age is part of the show's status quo, then [[StatusQuoIsGod you can expect his/her age to remain the same even after the "birthday episode"]]. The inevitable [[TwentyFourHourPartyPeople numerous guests and fancy decorations]] at his/her birthday party raise even more curiosity as to what this character's age is, as such a party would only seem to make sense during a monumental birthday like his/her 21st or 40th.

** Averted in "You're Getting Old
, which opened with Stan celebrating his 10th birthday.

* Lisa has had a number of these on ''WesternAnimation/TheSimpsons'' but remains 8. Averted in the episode where the mental patient who thinks he's Michael Jackson shows up, which I believe is when she turns 8, the age she will remain for the rest of the series.

This trope occurs most often in children's cartoons and more kid-friendly sitcoms. This is most likely because, well, [[FridgeLogic kids love birthday parties, and to them, every new age is significant.]] However, it also frequently appears in more adult works, where it is decidedly less justified.

* Related: In ''Anime/{{Pokemon}}'', the anniversary of Ash and Pikachu's meeting is celebrated at least twice, but everybody is still 10.

* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Sweet and Elite" centers on Twilight Sparkle's birthday among other things, though her age is never revealed.
** Likewise, Spike's age on his birthday is never revealed in "Secret of My Excess".

* Lisa has had a number of these on ''WesternAnimation/TheSimpsons'' but remains 8. Averted in the episode where the mental patient who thinks he's Michael Jackson shows up, which I believe is when she turns 8, the age she will remain for the rest of the series. In one episode Homer and Bart were going crazy with fireworks and blew up half her room.

This trope occurs most often in children's cartoons and more kid-friendly sitcoms. However, it also frequently appears in more adult works.

* Played similarly straight in the Nickelodeon ''WesternAnimation/{{Doug}}'' episode "Doug's Birthday Present." To the extent that the Disney series opened with an episode about him turning 12. Since he was 11½ when he moved to Bluffington and lived there during the Nickelodeon birthday episode, the only logical conclusion one could draw is that he had ''two'' 12th birthdays!

* Related: In ''Anime/{{Pokemon}}'', the anniversary Ash and Pikachu meeting is celebrated at least twice, but everybody is tstil ten.

* ''Series/SavedByTheBell'' inexcusably did this with Screech's and Zack's birthdays. Being that they're both in high school, there was no reason for them to not at least provide their new ages (which would've been anywhere from 15 to 18).

* ''CalvinAndHobbes'' had an arc were Susie invites Calvin to her birthday party. Her age isn't mentioned, but they all appear to be perpetually six.

* Sonic in ''VideoGame/SonicGenerations''; it can be assumed that he's still 15 years old.

* Played completely straight with the ''WesternAnimation/{{Rugrats}}'' episode "Angelica's Birthday." To the extent that, in a later episode ("Pickles Vs. Pickles"), her parents say that she's still 3 years old.
** Averted, though, in the aptly titled "Tommy's First Birthday."
* Played similarly straight in the Nickelodeon ''WesternAnimation/{{Doug}}'' episode "Doug's Birthday Present." To the extent that the Disney series opened with an episode about him turning 12. Since he was 11 1/2 when he moved to Bluffington and lived there during the Nickelodeon birthday episode, the only logical conclusion one could draw is that he had ''two'' 12th birthdays!
* The ''WesternAnimation/SouthPark'' episode "Damien" does this with Cartman's birthday (although we can probably assume that he turned 9 in this episode, as the show subtly suggests that he's a little older than the other three SP boys).

* [[LampshadeHanging Lampshaded]] in an episode of ''WesternAnimation/TheMagicSchoolBus''. It's Ms. Frizzle's birthday and the class goes to a bakery. During the AndKnowingIsHalfTheBattle segment at the end, a kid goes there and tells the baker shown in the episode that one critical piece of information was missing from the show: they never said how old Ms. Frizzle is.

* Lisa has had a number of these on ''WesternAnimation/TheSimpsons'' but remains eight. Averted in the episode where the mental patient who thinks he's Michael Jackson shows up, which I believe is when she turns eight, the age she will remain for the rest of the series. In one episode Homer and Bart were going crazy with fireworks and blew up half her room.
* In the ''WesternAnimation/SpongebobSquarepants'' episode "Spongebob Meets the Strangler", Spongebob celebrates his birthday among several other parties he planned on the same day. Even though he has a revealed birthday, his age isn't revealed.
* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Sweet and Elite" centers around Twilight Sparkle's birthday among other things, though her age is never revealed.
* A "US Acres" segment on ''WesternAnimation/GarfieldAndFriends'' had this for Roy.
