So why "Pill"

Anyone who thinks the pill bit is a reference to a couple of the kids slight addictions to questionable substances ...you are so wrong . In fact I've seen plenty of footage of the guy and never have a seen a man so wealthy with such pilled sweaters. He is sitting on the lawn at Hickory Hill with four of the kids in one clip and they are pulling up grass .......how did they not start picking at Dad's jumper.They didn't have those little electric sweater shavers I guess. Anyhow I am kidding because his scruffiness in comparison the J.F.K's super smart-ness is only one of his most endearing features.
