Teensy Things

Little, little, little, Tell me how much I need to- Whittle, whittle, whittle, Whittle it down, get teeny tiny small- What's the smallest word you've ever heard? Or, the smallest thing and its word? Hey, ancients thought it was sand for a long time, That's a big question to set to rhyme- Is it the itsy bitsy teenie weenie yellow polka dot bikini? Ya know, the one she wore at the shore. Or, is there really more? Is it like a bit or a byte? Now that's so trite. Is it like a pixel or bik? Sounds like a trick. Then it must be smaller. Yikes! I'm gonna holler! Wait, give it a chance. Let science advance. It may be an atom or molecule, maybe a proton. More likely a quark, neutrino or even a Preon. Sure hope it's not a singularity in a black hole. Or possibly theoretical like a Plank particle. This stuff's a bit beyond me. It's all below the size of anything measurable. Now that bikini song, that was pleasurable!
