When they moved across the country, Harvey and his wife decided to drive both of their cars. Nathan, their eight-year-old, worriedly asked, "How will we keep from getting separated?" 

"We'll drive slowly so that one car can follow the other," Harvey reassured him. 

"Yeah, but what if we DO get separated?" he persisted.

"Well, then I guess we'll never see each other again," Harvey quipped. 

"Okay," he said. "I'm riding with Mom."
