Fred and Madge seem to be the stereotypical middle-aged couple, bored with each other, talking in clichés. But it turns out that Fred's job is to push boulders up-hill like Sisyphus and Madge's is to sieve water all day long. Further, since the action is repeatedly interrupted by a figure like a director, it seems as though they are inhabiting a play about themselves. Soon it is clear that London is being subsumed by rampant greenery and the whole cast goes into ecstasies of escape … The play is full of one-liners and the dialogue reeks of hilarious social and sexual innuendo
