4x13 - Ally McBeal

Ally has hallucinations with Barry Manilow. Richard assigns Ling to work with Jackson Duper, the firm's newest lawyer. When they meet, Ling discovers that Jackson slept with her in the past under a fake name. They have to handle a double case of a man who wants his marriage annulled because his wife is a nymphomaniac and cheated on him 106 times and is suing the minister for having a torrid affair with her. Between the unisex bathroom, Elaine's vibra and Melanie's Tourette, Jackson is going crazy with his new job and questions his future in the firm. Meanwhile, John proposes to Melanie. But Melanie doesn't want to be institutionalized (even if that institution is marriage)...
