S5·E11 Zena's Honeymoon

Zena comes to the garage and announces she's getting married and asks the gang to let Louie know that she wants to speak with him. After telling Louie, he becomes convinced that she wants to get back together, and he meets her for dinner. Louie is crushed when she tells him she's getting married and wants him to attend, and he reacts very insultingly toward her. The rest of the gang goes to the wedding when Louie refuses, but afterwards he regrets not going and wishing her well, so he crashes his way on to their cruise ship (about to leave on their honeymoon). Zena and her husband are not happy to see Louie and before he can wish them well, Louie has a change of heart and starts choking the husband. After composing himself, however, he wishes them well, and Zena seems touched.
