Sylvie Cardenas (played by Lillian Hurst) is Ernie's mother and Pepito's wife. She is morbidly obese and needs assistance with bathing and dining. She is deeply religious, but she was pregnant with Ernie before even marrying his father, Pepito Cardenas. Ernie refuses to believe so, even though there are pictures of him being breastfed at the wedding reception. George also accidentally saw Sylvie naked as a child. He claimed he saw one boob through one window and the other boob through the other window. Then Ernie Cardenas said that she likes to air dry.
