A little more than a year ago, I went to a small hole in the wall bar and had the unbelievable privilege of watching Neil Hamburger (arguably one of the best working stand up comics in the world) form a mere 2 feet away. During his set, a man kept finishing his jokes for him until Mr. Hamburger, had something to say to the heckler. Watch the genius at work:
You might recognize Neil Hamburger from "Tim and Eric Awesome Show: Great Job!", "Tenacious D and The Pick of Destiny" and the upcoming "Hamlet A.D.D"
