A man called his mother in Florida. "Mom, how are you?"
"Not too good," said the mother. "I've been very weak."
The son said, "Why are you so weak?"
She said, "Because I haven't eaten in 38 days."
The son said, "That's terrible. Why haven't you eaten in 38 days?"
The mother answered, "Because I didn't want my mouth to be filled with food if you should call."
