“It takes about 13 facial muscles to smile and about 87 to frown’’ says 83-year-old John Clement. Laughter and good humor connect the generations of the Clement family. Daughter Lawrason Clement brings out her father’s best stories as they chuckle through decades of family lore, including the time his infant great grandmother “disappeared,’’ only to be returned safely by a baboon, the trip that persuaded his father to buy him a Shetland pony and the honor of rubbing elbows with famous politicians and important leaders.
