4) Across from the performing guy there's another comedian performing by himself with nobody paying attention to him. Investigate a bit then go talk to the dude without spectators and agree to help him. Go back to the marketing agent of the dude with the head and convince him to go help the dude that doesn't have anybody. Once all the spectators leave go talk to the dude that's now alone with the head and tell him his agent has left him. He'll go over there all mad and you'll be left alone with the head which you can now grab without a commotion.
