One's named Newtie; the other, Georgie Porgie

We decided that the shorter, rounder one looks lots like Newtie Poot, at least in some lights and from some angles, and that the taller one resembles another well-known public figure, a three-initial person whose pater is a four-initialed person. The second couplet has some relevance. No matter how the blade carves the cucurbit, the result is always expressive.
