Doctor in the House S10E06 - It's All Right, I Am a Doctor

To the jealousy of some of his colleagues, Paul becomes a national celebrity as the Monday Medic on breakfast television, with his catchphrase 'It's all right, I am a doctor'. He gets a column in women's magazine Twenty-Something where he is invited to conduct research on why young women are attracted to older men, and finds himself smitten by the American researcher working with him. However it turns out that she was only using him, as her marriage to him would have given her a work permit.
