Inspired by this toy. From the site’s particularly inspired description:
“The elegance of our golden shrieking chicken is surpassed only by its practicality. Simply give her a squeeze and you’ll enjoy hours of old-fashioned, battery-free hen squawking. Gather the kids and play a game of Whose Ears Hurt First? or discuss the merits of annoying, repetitive sounds. Perfect during meditation, or at your next interdepartmental meeting. Skillfully molded from plastic.”
There’s a YouTube video (warning: TURN DOWN THE SOUND) if you really need a demo (hint: you don’t).
