Gremlins are annoying, frustrating, incorrigible creatures completely devoted to Mischief in all of its mischievous forms: missing socks, lost keys, mysteriously broken toys, malfunctioning electronics, dead batteries that (you swear) you just replaced, tacks on the ground, morning alarms going off (when you’re sure you turned them all off),
oven timers not going off (and burning the whatever-it-was-you-were-cooking), gates left open, glasses left on the chair, toothpaste switched with frosting, glasses of water switched with vinegar, salt instead of sugar, clogged toilets… Such is the handiwork of your average, happy, industrious, absolutely annoying Gremlin.
