P.G. Wodehouse 
Laughing Gas 

“ A lifelong treat “ Simon Garfield , Esquire
A P.G. Wodehouse novel
Joey Cooley is a golden-curled child film star, the idol of American motherhood. Reginald, Third Earl of Havershot, is a boxing blue on a mission to save his wayward cousin from the fleshpots of Hollywood. Both are under anaesthetic at the dentists when something strange happens – and their identities are swapped in the ether.
Suddenly Joey can use his six-foot frame to get his own back on his Hollywood persecutors. But Reggie has to endure everything Joey had to put up with in the horrible life of a child star – including kidnap.
Laughing Gas is Wodehouse“s brilliantly funny take on the “If I were you“ theme – a wry look at the dangers of getting what you wish for in the movie business and beyond.
