One never expects one Standing *****, Straddled with club in hand; There's a postage stamp With pole and flag Daring resolve and grit; So one checks one's stance, Sneaks a glance And slightly adjusts one's grip; Then a reaction occurs Like controlled fussion, And out of confusion comes sense. The contact cements a crack and launch, Startling one like a gun; One scratches one's head, Dumbfounded and red, One's aced a hole-in-one.
Number four, but the word one appears twelve times in this poem. Eight to go.
