It is another odd couple who almost steal the Odd Couple movie. The 'Coo Coo' Pigeon sisters on their disastrous double date with Mattheu and Lemmon.
Cecilly & Gwendolyn are two British characters, played by Monica Evans and Carole Shelley, of such charm and humour one can't help but warm to them. Which Lemmon's Felix does, leading to him ruining the evening for Mattheus's Oscar.
