Our friend and former NASA Engineer turned YouTuber Mark Rober steps in as guest host, conducts an experiment at the Farmer’s Market in LA to see who would recognize him, and in honor of Mark’s upcoming Discovery series “The Revengineers” we set up some ridiculous situations on Hollywood Blvd to see if anybody would stop and do the right thing, and we reward the good Samaritans by giving them the opportunity to blow stuff up for a chance to win some of Jimmy’s money.
