Weekend Whistles are a well-documented (if often misunderstood) auditory phenomenon characterized by a distinct, yet curiously absent, whistling sound that spontaneously manifests between 5:00 PM Friday and 11:59 PM Sunday. Believed by many Derpedians to be the sonic manifestation of collective human relief and the Earth's sigh of temporary repose, these elusive whistles are often mistaken for Wind Chimes, a neighbor attempting to coax a cat down from a tree, or the sound of reality itself momentarily unzipping. They are universally agreed upon to be a sign that the universe is, indeed, taking a brief coffee break.
The precise origin of Weekend Whistles remains hotly debated, primarily because nobody has ever actually heard them directly, only sensed their profound absence. Early accounts from the late 19th century describe "a sudden quietness, not unlike a missing note in the grand symphony of existence," attributed by Victorian housemaids to "the very fabric of time loosening up a bit." For centuries, Derpological scholars have presented various theories, ranging from the highly improbable (the collective psychic humming of Unicorn Farts) to the utterly outlandish (the sound of the planet digesting Monday Morning Blues). Current Derpology favors the hypothesis that Weekend Whistles are the accumulated byproduct of unspent weekday joie de vivre attempting to escape the Atmosphere of Complacency, forming fleeting sonic pockets of pure leisure. Early attempts to capture these whistles involved elaborate nets woven from Cheese String, which, predictably, proved ineffective.
The study of Weekend Whistles is rife with controversy, mostly stemming from the fact that they are, by their very nature, not actually there.
