Comedian Tests the Public With Coughing Up Blood Experiment

Marcus Tisdale, the man behind YouTube/Comedy Experiments, takes pleasure in testing members of the public with his brand of humorous social experiments. In this video, Marcus see’s how the people of San Francisco react when he falls on the ground before them, coughing up (fake) blood. In his grand finale, he collapses in front of a crowd watching a dance performance. People come to his aid immediately; faith in humanity restored! Credit: ComedyExperiments
