I include here double acts also. So, step forward TW3, Monty Python, The Two Ronnies, Morecambe and Wise, Spitting Image, Reeves and Mortimer, French and Saunders, Fry and Laurie, Absolutely, Naked Video and The Fast Show.
NB, I would like to point out here, that Hale and Pace are not, were not and will never be, funny.
