From The Shakespeare Requirement by Julie Schumacher:

"Janet had endured, during the remainder of her father's visit, a Moebius strip of parental observations: he never understood why Jan-Jan had married that loser; she was obviously better off without him; her ex was a self-satisfied clod and a jackass; and who was that sexpot he was walking with?"
