@DavidEduardo alluded to, it was most likely just a "bit". Could have been spontaneous, could've been rehearsed or planned. In reading your posts it seems you may be taking their comments too seriously and overthinking them. Remember, first and foremost these "personalities" are entertainers and their job is to connect with their audience and be relatable. That sometimes includes including real-life details about things they've done recently, concerts they've attended, or things around the studio which their audiences can somehow relate to. Other times that may mean taking a minor occurrence and exaggerating it to the audience for comedic effect or to make it a more exciting or dramatic story than it was, or at times, they create stuff out of thin air or as David explained, creating and developing characters.
