At first Fielding appeared the amicable nebbish, in the swim and in complete accord with the vibrant social whirl of The Society of Floridian Lawn Bowlers, but at heart he was a savage, a troglodyte, a demented maniac set on a course that, to the dismay of us all, crushed us beneath his unyielding will until we were forced to suffer the vicissitude of a digital score board driving poor Bergeson from his position as “chalker” and leaving him a broken and weeping heap beneath the new technological marvel.

"Sure it's just dandy being right in the swim of things, but as the conference's chief negotiator I was nonplussed when up gets Mr. Shalom yet again (at 3 a.m. mind you) and addresses the Chair as 'a complete nebbish'; so not wishing to reveal my ignorance I joshed with him, responding amicably 'No, you nebbish, me English, actually, old boy' . . . at which point, blow me, but he and his delegation leave the assembly protesting angrily about constant vicissitudes and prevarications - as if I wasn't doing my level best!"
