In practice, the last rule has no effect as the end of the sentence is declared almost entirely arbitrarily by Humph sounding his horn , but it does at least set the tone for the round, which sees the teams construct a long, unwieldy and often nonsensical sentence, generally including as many silly turns of phrase as possible.
For example, one sentence included this fragment: '...cavorting wildly over a cliff, who was in wuthering mood...' which confounded expectations twice in less than two passes round the four panelists, firstly 'cliff' is taken to refer not to a wall of rock, but rather to veteran rocker Cliff Richard and secondly 'wuthering' does not receive its expected continuation 'heights' (Richard was appearing in a stage production of Wuthering Heights at the time).
