I'm not so sure it'd be dishonest unless they lied about who they were when they interviewed someone and purposely misled someone who had never seen the show during an interview. That said, though, it does make sense to me (in hindsight.. :P) that they'd rather script and control the process than rely on luck/talent in getting a good set of shots to use - after all, it's a big business and sending a film crew + on-air talent all over the country (or world) to film could get rather expensive if they couldn't be assured of being able to make the required joke(s) afterward.
