All of which is richly laced with rib-shaking humour both for adults and children. There are the whoopee-cushion effects when someone sits down on a pile of rags that turns out to be Friar Tuck; or the moment when an enemy of Robin discovers he has a pole stuck up his nose. For slightly older children, the self-consciously theatrical introduction, where, for instance, one actor explains that he will play "the whole Sheriff 's army, and a dog", should prove a harbinger of the tongue-in-cheek narrative to come.
