I'm quite sure you're mistaken in thinking that this is something that only happens in Telugu films. All of those things happen all across Indian cinema.
Farcical comedy, as a genre, is an artefact once perfected by Telugu cinema. Jandhyala's movies certainly had farcical characters even if the plot showed a semblance of sense. From there, things got even more exaggerated (which is welcome in a farce), and we started watching films with hyperbolic plots involving a man pretending to be a woman for the sake of accommodation (Chitram Bhalare Vichitram), a man whose lifestyle and passion were small loans (Appula Apparao), and a pair of twins who not only looked alike but also compulsively moved alike when in proximity (Hello Brother).
