Dr. Greenberg is a remarkable inventor who creates all kinds of inventions that help the Jews keep Torah and mitzvos.
But Dr. Greenberg regrets that he is not more of a talmud chochom; if only he did not have such a big Yetzer Harah to bother him every time he tries to learn.
And so it is that one day Dr. Greenberg has a real brainstorm: to invent a Yetzer Harah Machine, to have his Yetzer Harah taken out of him!
And so Dr. Greenberg, with the assistance of his faithful robot, Uzi, invents the Yetzer Harah Machine, and Dr. Greenberg operates it on himself, removing his Yetzer Harah from within him.
But this turns out to be a sad mistake – for Dr. Greenberg’s Yetzer Harah, who looks just like him, is quite strong, and he ties up Dr. Greenberg, and goes on a rampage to do all the aveiros that he can!
Things go from bad to worse when Dr. Greenberg’s Yetzer Harah essays to take over the construction site where a brand new shul is being built – in order to have a mansion built for him instead, and builds a huge army of fighter robots to achieve that end.
Now Dr. Greenberg must find a way to escape, and catch his Yetzer Harah.
For he has now learned a most valuable lesson indeed: The goal of every Jew must not be to get rid of the Yetzer Harah, but to fight the Yetzer Harah!
