V. Honour Your Father and Your Mother.
"Honor your mother and your father" Homer is constantly disrespecting his father. In one episode Homer won't stop the car for Grampa to get out and use the
washroom in "Homer Simpson in "Kidney Trouble"". Grandpa's kidneys burst and Homer has to donate one of his for his father. But he doesn't. He takes the chance of his father dying and runs away. Grandpa gets the Kidney at the end, but it is because Homer is already in the hospital for an unrelated injury. He is constantly making jokes about his father and treats him as if he was a child. When Grandpa is working at Sprall Mart Homer says "how dare you challenge what I think old people can do?" Homer does not distinguish between his father and other older people.
