An attractive, or whimsical yet unexpected rarity/oddity; something that would cause a person, at the sight of it to say, "Wull gee, aint that somethin?" Such as finding a two dollar bill folded into a crane under your seat at a football
game, or finding some petrified wood that still looks exactly
like a stick, or a two-headed jackal-ope in a taxidermy shop, or a mini-
cooper with giant tires and hydraulics.
Well I'll be darned ... aint that a
blond duck of all things? A mobile cheese
shop that goes around via a cow-shaped blimp... I will
indeed be darned.
