Viral video goofball collective Chad, Matt, and Rob introduced YouTube to their interactive narrative series “The Time Machine” last December. The LA-based, Lonely Island-affiliated “dot comedy” foursome (somehow Jonah Goldstein didn’t warrant name inclusion) have since one-upped themselves with “The Murder,” a choose-your-own-adventure for the Web. At the end of each segment, click the path you want to follow (in comic-book panel form) to save Rob. We can’t wait to see what directions this approach can take with a little budget behind it.
