They say you should never bring a knife to a gunfight, but what about a spoon to a sword duel? 

In the latest clip from Mark Gatiss' Robot of Sherwood, the Doctor faces off against Robin Hood's sword with nothing but an ordinary piece of cutlery – a Robin Hood, it should be noted, that he can't believe exists. Clara is thrilled about it, though. 

Check out the clip below.  

Robot of Sherwood is on BBC1 at 7:30pm on Saturday 6th September
