A small tribute to my favo(u)rite show currently on, whose season finale airs this weekend and which has been renewed for a fifth and final season. The rare show that makes me feel stupid (I sometimes have to put on subtitles to make sure I get everything). I'm not going to explicitly name the show, if you know you know. A major hint - it airs on Monday nights on BBC One (though I think it's more of a Channel 4 type show).
