Joke

There was an elderly man and his hard of hearing wife travelling from Memphis to Nashville. The trip was progressing along fine until they began having car trouble. Pulling into the nearest gas station the mechanic struck up a converstation with the old man.
"Where are you headed?" Asked the mechanic
"Nashville." replied the man. "What did he say? What did he say?" asked the impatient and virtually deaf wife. "He asked where we were going and I told him, Nashville."
"Where are you coming from?" Inquired the mechanic.
"Memphis." replied the old man. "What did he say? What did he say?" again squawked the old woman. "He asked where we were from and I told him Memphis."
"Memphis." sighed the mechanic. "I once knew an old lady from Memphis that was the meanest, rudest, ugliest, old bag that there ever was. She’s the reason I moved here."
"What did he say?" squealed the woman.
"He said he thinks he knows your sister."
