This is a challenge for you. This video is called the Laughter Chain, which lasts about 4 minutes. The challenge here is to see how long you can last watching the video without laughing. I lasted a good minute before I couldn't help myself but laugh. :lol: How about you guys?
Try not to laugh.
And if you claim to not laugh during the whole 4 minutes, you are lying. It's guaranteed that you will end up laughing.
