Use April Fool's Day this year as an excuse to ditch the routine and share a few laughs with your family.
Laughter is infectious. The sound of roaring laughter is far more contagious than any cough, sniffle or sneeze. So if you need a quick dose of the wild variety, check out the pair of spotted hyenas at the Lincoln Park Zoo. Kai and Phika are the first hyenas to live at the zoo since the 1970s. So why do they call them laughing hyenas anyway? Because they sound like people laughing their heads off! You can find Kai and Phika on the northeast side of the zoo in between the Sun bear and the Andean bear.
