As heard in Animaniacs:"I'd like a small popcorn, please.""We don't have small.""What do you have?""Large, Extra Large, and Super Chubby.""Wouldn't that make a large a small?""I'll have to ask my manager."While you're at it, lad, ask if he can explain a similar semantic discrepancy plaguing America's family transporter, the minivan. The "van" part is spot-on, but for something that stretches longer than a pole vault, stands taller than the average adult, and can haul away half the contents in Wells Fargo's safe, is "mini" really the word that springs to the surface?It did once, back when the original Dodge Caravans and Honda Odysseys roamed the land. But ever since those tidy street shuttles underwent their dramatic overnight growth spurts, Mazda has been taking a lot of flak for its "too small" and "underpowered" MPV. Hey, everyone responds to pressure differently. For its new minivan, dubbed the 5, Mazda has opted to take that MPV, shrink it, lop off two cylinders, and subtract 43 horsepower. Huh?Whatever you make of the product, let's score one for truth in labeling.
