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