Episode 7 of "Angel"
s01e07 The Bachelor Party

Just as Doyle is inches away from finally making a connection with Cordy, his estranged wife shows up at Angel Investigations begging for a divorce so she can marry the new love of her life. After the initial shock of it all, Doyle agrees to consent to the divorce. Meanwhile, Angel discovers that the fiancee comes from a long line of pacifist demons, but this doesn't seem to rock anyone's boat. After Doyle consents to the divorce, the fiancee invites Doyle to join his bachelor party. Unbeknownst to Doyle, the fiancee's family has a ritual to fulfill: the fiancee needs to eat Doyle's brain in order to have a successful marriage. As the party proceedings begin, Angel gets suspicious and wanders upstairs. There he discovers these demons may not be as pacifist as they seem. He is ejected from the restaurant by the family. Downstairs, Doyle is about to be eaten with a shrimp-fork, but Angel and Cordy and the fiance arrive on the scene and come to the rescue.
