Mort (the Griffin family's Jewish friend) goes to the Griffin family's house and needs to use bathroom. He thinks that Stewie's time machine is a bathroom and goes inside. The time machine takes Mort somewhere in the past. Mort can not go back to the present because he does not have a return pad (a machine that will take him back to the present). Brian and Stewie get a return pad and go to the past. They learn that Mort is at Warsaw on September 1, 1939, right before Poland is invaded and World War II starts. Mort is in a synagogue with his ancestors.
