Ep 16. Boo! (a.k.a. I'm With Her)

Frasier gets annoyed when Martin constantly sneaks up behind him and scares him. Since he has a clown suit for use in therapy in dealing with one of his patients who has a fear of clowns, he decides to get his revenge on Martin by dressing up in the clown suit and pretending to attack Martin with a meat cleaver. Unfortunately, he scares Martin so much that he has a mild heart attack and ends up in hospital. While he is recovering, Martin asks Ronnee to marry him.
