3 - 24: That Pistol-Packin' Hermaphrodite

Charlie and Mia start making their wedding arrangements with the help of Alan. Things begin to fall apart when their two families meet each other at a meal and the meal ends up being a complete disaster. After a heated argument, Charlie and Mia eventually decide on a small ceremony in Las Vegas, but Charlie calls it off at the last second because Mia announces that she wants Alan to move out to make room for a nursery. Alan then spontaneously proposes to Kandi, and after she says yes, Alan announces that he will be moving out of Charlie's house anyway. Title quotation from: Charlie, talking about Mia's police officer sister.
