I originally started watching Coupling because of Jack Davenport, who I am a fan of.
I LOVED this episode. It was hilarious. It almost made me cry from laughing so hard. I love Steve and Oliver, infact I love them all.
I'll admit that I haven't watched that many Coupling episodes, but I've watched enough, and so far this will be one of my top favorites. The idea of a whole episode being dedicated to phone call between an insane amount of people, some of which are just a room apart, may seem boring and stupid, but it's a great episode, funny, very funny. Two big thumbs up! (Had to slip in the pro reviewer lingo =D)
