Watch: Jon Stewart, Jimmy Kimmel, Stephen Colbert and John Oliver Get A Workout For #GiveThem20

Social media activism has really been gaining momentum since last summer’s viral ALS Ice Bucket Challenge, and this summer’s new craze may be ACP’s #GiveThem20 challenge, which calls for military veteran supporters to do 20 push ups, film it, put it on social media and then and challenge friends to do so as well. Celebrities usually have a critical role in igniting memes like this, and #GiveThem20 has garnered support from late night hosts Stephen Colbert, John Oliver, Jon Stewart and Jimmy Kimmel to get the ball rolling. Each one of the hosts added their own comedic flair to their videos, and called out other celebrities to do the challenge.
