‘Game Of Thrones’ stars joined the #ShareTheLaughter challenge. They believe laughter helps during dark times and it can be as good as medicine.

‘Sesame Street’ launched the #ShareTheLaughter challenge to spread joy and encourage good laughs around the world. The idea is simple: you tell your friends or family members a joke and encourage them to do the same.

‘Sesame Street’ has been posting funny videos of stars doing the challenge. Many celebrities joined, including Kit Harington and Gwendoline Christie. ‘Sesame Street’ has already paid tribute to the show in 2015 by launching a series of short videos called ‘Game of Chairs’.

GOT starts aren’t the only ones who accepted the challenge. Starts like Padma Lakshmi and Josh Groban have participated as well.
