Comedian Katherine Ryan gets Adam Hills, Josh Widdicombe and Alex Brooker in line as Day 6 hits its crescendo. There's a very special performance from six-time Paralympic gold medalist David 'Weirwolf' Weir, and para-triathlete Lauren Steadman joins the gang. Expect all the usual irreverence, plus sketches, clips, and the taboo-busting #isitok questions from viewers and fellow athletes.
