Elroy "Lucky" Kleinschmidt, age 38, is Luanne's husband and Gracie's father. He got his nickname from an incident at a Costco store where he went in to buy a new winch, realized he had to use the restroom, and slipped in a puddle of urine, injuring two of his vertebrae requiring them to be fused together. The resulting injury left Lucky in constant pain. He received a $53,000 cash settlement from the store to keep him from suing them, which caused his friends to see him as lucky, hence the nickname.
