Koala Spit-Takes Have Limited Comedic Impact
The “spit-take” is a time-honored comedic tradition in which a character receives a piece of startling news while drinking and spits the beverage in shock.
As Koala Bears spend the majority of their day munching on eucalyptus leaves, their ability to execute a spit-take is limited. The leaves may fall gently from a bear’s open mouth, but the impact is not nearly as great.
