The joke machine flies across the UK, on a quest for the most side-splitting, rib-tickling and jaw-jiggling jokes, leaving no punchline unturned and no gag untested.

Jokers from two schools are zapped up into the joke machine, where they are expected to deliver their funniest joke. Impress the Joke Master and they could help their school to victory, but fail to hit his funny bone and the joke machine is equipped to punish. From smoke, splats, stamps and blasts, the feisty banter between master and joke teller can lead to unpredictable consequences.

This episode's victims - ahem, we mean jokers - are Dunblane and Emmaus. Show less
