The Spoonbill Generator

My penchant's mathematical [Apsley]

Where curvature's concerned [Roland]

While Newton's on sabbatical [Kansas Sam]

Where thievery's the nub [Kansas Sam]

And not shrill or logical [jm]

For those who reason snub [P]

You see it's still methodical [jm]

This proof of Newton's filch [Kansas Sam]

It added up to zilch [jm]
