1x24 - "George Lopez" Reunion

December 15, 2009

After George's opening standup, which was G-rated due to all the kids in the crowd, "Creepy Little Sitcom Mom" (Belita Moreno) paid a visit to deliver bad news about George's old haircuts, among other things. Belita then joined George on the stage to reminisce about their work together on the show. She also admitted to stealing a few mementos from the set. Constance Marie joined them and talked about the early days of the sitcom, when George was a novice actor... and how George's real-life wife cast her as George's sitcom wife! Then, Valente Rodriguez joined the party -- the guy who can make George laugh like no one else can. George welcomed the kids from the show -- Luis Armand Garcia, Masiela Lusha and Aimee Garcia. They thanked George for the experience of working on "George Lopez" and talked about how their lives have changed since then. George got teary-eyed as he shared his thoughts on what the show means to him. Then came the "George Lopez" finale they never got to make, which included a cameo by Leah Remini.
