In July 2014, Benny and Rafi Fine, also known as TheFineBros, released their new React channel, packed with tons of videos of reactions by kids, teens, adults, and elders. One of their segments, Try to Watch This Without Laughing or Grinning, includes showing a Reactor a bunch of viral videos, and testing that Reactor's ability to stay as stolid as possible. Here are some of the best clips that we have seen from their show. Try to watch these without laughing or grinning!
