Mooney's Other Wife (6x18)

:

Mr. Mooney flirts innocently with a waitress when attending an out-of-town bank convention. But then the sexy server comes to L.A. insisting that Mooney has proposed to her. To scare her off, Lucy pretends to be Mrs. Mooney and shows the homewrecker how horrible it is to be married to a such a monster.
