Laugh your hearts out this Sunday (Aug 19) as Kuya Kim Atienza and Melai Cantiveros find out the origins of laughter and pull hilarious pranks in “Matanglawin.”

Doctors may say that laughter is the best medicine but Kuya Kim also proves that one can also die from too much laughing. In fact, there’s even a sickness called mass psychogenic illness or mass hysteria where people suffer contagious laughing attacks.

Melai then puts this to test as she pulls pranks with the madlang people, man-sized bees, and a gorilla.

Also, find out what tickles a person’s funny bone and if a funny bone really does exist in the human body.

Don’t miss all these in another exciting episode of “Matanglawin” this Sunday (Aug 19), 9:15 AM on ABS-CBN.
