Just Not Cricket is an episode of The Sooty Show
Matthew is invited to a cricket match and once again claims that he's an expert. But the others feel that he is just boasting again and remind him of all the times he said he was and always messed it up. However the match gets cancelled and he challenges Sooty and Sweep while Soo umpires to make sure there's no unfair play.
Matthew is just as boastful as ever and goes to extreme lengths to win by cheating making Sooty and Sweep look silly. The others get their own back though when Sooty gets out his self cricket bowling machine (That he magiced up earlier) that is too much for Matthew and makes him leave the pitch taking away his points.
Back home the others make Matthew promise once again not be big headed and boastful, be a better loser and apologize for his rude behaviour.
