The running gag is a very interesting humorous tool that will be a trend in 2025. It is a joke, joke or joke that is repeated. The good running gag is not very funny the first time, it is when it is repeated that it gains strength. But it is not without its dangers. The Cruz y Raya one is «muu cansiiinooo». There was also the rhyming with the five (every morning I wake up I thank life that it is no longer used).
From time to time running gags appear and become fashionable and everyone uses them, until they disappear. At home we are against fashionable running gags and have banned them. A good running gag has to be homegrown. It has to be born in a real environment and in a shared culture of life. Not on TV. I encourage you to try a running gag with someone close to you today.
Edit: According to the English edition of wikipedia catchphrases are not considered running gags.
About running gags on wikipedia: Running gags may begin with an instance of unintentional humor that is repeated in variations as the joke becomes familiar and the audience anticipates the joke's reappearance. The humor in a running gag may derive entirely from the frequency with which it is repeated, but the underlying statement or situation will always be some kind of joke. A trivial statement will not become a running gag simply by being repeated. A running gag can also derive its humor from the (in)appropriateness of the situation in which it occurs, or by priming the audience to expect another occurrence of the joke and then substituting something else (bait and switch). Running gags are found in everyday life, live theater, live comedy, television shows, video games, movies, books, comic strips, and potentially any other situation in which humor is possible and there is sufficient time for repetition to occur.
A running gag can be verbal or visual and can «convey social values by echoing belligerent speakers with a barrage of caricatured threats.» For example, a character may present others with a proposal that is so ridiculous or outrageous that it is likely to be a mockery of himself to the point where the original request has little or no chance of being carried out and results in a humorous effect.
