What would a wedding be without family? Peaceful, say Erin and Titus in this second-season finale. While making plans with their priest, they decide to marry right then and there, thus averting what they see as definite disaster. A wise decision, but unfortunately undone by Tommy's big mouth. Nightmare by nightmare, people start showing up. Soon, the church ""is full of people we love,"" says Erin. ""How could this go so horribly wrong?"" replies her fiancÃ©. Most notable on the nonguest list: Titus' mom and her latest spouse , whom Titus catches in an act that puts a hitch in the hitching.
