Bill Maher: This is the mount of olives. A lot of orthodox Jews want to be buried here, 'cause they believe that when the messiah comes, he will raise them from the dead and march them through that golden gate and onto the temple mount, which is why the Muslims have walled up the gate. The better to keep out the Jewish messiah and his kosher zombies from getting in. Although you'd think that if you had the power to raise the dead, you'd have the power to jump a fence.
Bill Maher is poking fun at the fact that a wall has been built to block the Jewish Messiah yet if he has the power to raise the dead why cant he hop over a fence.
