why are so many comedy shows like eachother

damn near every comedy anime ive watched has the same jokes and nearly the same like my first comedy show was saiki k and then iw atched rom coms which are all copy pasted and then i watched some niche ones and they were ok but all the people are nearly like eachother with some are pervy some are stupid its all the same some guy says something stupid and a girl punches him into the sky like what anime is actually diffrent dont recommend me stuff like konosuba or hinamatsuri i like stuff dubbed but sub works too if its really peak and i like prison school but not too much fan service
