Squirrels Hibernate So Hard You Can Juggle Them
This has actually been proven by science.
Anybody who's observed squirrels knows they're manic little buggers: hopping from place to place, chattering excitedly, in general acting like they just robbed the Pixy-Stix factory and are tweaking off the spoils of their labor.
But there's another half of a squirrel's life that's the polar opposite: a secret time, full of endless hours of deep, soul-satisfying slumber. During this restful period, you could take a squirrel and Hail-Mary pass it across the room, pretend to make it do an Irish jig, or even juggle it with other squirrels—and that last fact has been proven by god-honest science.
