A few guppies short of an aquarium. A few inches short of a foot/yard. A few kernels short of an ear. A few kopeks short of a ruble. A few links shy of a chain. A few measures short of a staff. A few open splices. A few peas short of a pod/casserole. A few pickles short of a jar. A few pies short of a holiday. A few planes short of an Air Force / hangar. A few points short of a polygon. A few revisions behind. A few sandwiches/apples/ants short of a picnic. A few screws loose. A few shrimps short of a barbie. A few spoons short of a full set. A few straws shy of a bale. A few tiles missing from his space shuttle. A few tiles short of a successful re-entry. A few too many lights out in his Christmas tree. A few volts below threshold. A few yards short of the hole. A flash of light, a cloud of dust, and… What was the question? A gross ignoramus — 144 times worse than an ordinary ignoramus. A hop, skip, and jump from success, but to get there he’d have to give up chewing gum. A kangaroo loose in her top paddock. A lap behind the field. A little light in his loafers. (Apparently offensive to some? Sorry.) A looney tune.
