A member of the Country Club asked the lifeguard how he might go about teaching a young lady to swim. "It takes considerable time and technique". replied the guard. "First you must take her into the water, then place one arm about her waist, hold her tightly, then take her right arm and raise it very slowly". "This is certainly most helpful" said the member. "I know that my sister will appreciate it". "Your sister?" said the lifeguard. "In that case, just push her into the deep end of the pool. She'll learn in a hurry".
