Your delicate mumble, is really no rumble, Oh wonderful, trundle wheel. The Ruler's so tedius, boring and plain, Endless repetition, Of its spacial position, Risks jumble avoided by wheel of trundle. To fathom a tumble, Or measure my uncle, The wheel gives no reason to moan or to grumble. Vernier callipers? No thanks, not for me! Your shape is so spikey, Not matching so nicely, The rotundity trundley wheel. As forwards I bumble, With you I can't stumble, As long as I trust my companion who trundles. Dear RADAR, you could learn a thing or two, From the wheel's clever simplicity, Requiring no electricity, Oh, humble trundle wheel. A hot apple crumble, or vascular bundle, Both lengths you will know if beside them you trundle. Micrometer, why measure so small? God's world is so vast, Won't fit in your grasp, The trundle encompases all. The bumbly, trumbly, Humbly, mumbly Wonderfully trundly wheel.
