One of the finest bits of wisdom from Al Bundy. He never cleaned his barbecue grill because the leftover bits helped flavor the cooking. "Ashes from the past for burgers of the future", as Al says.
Hilarity ensues when Kelly cleans the grill, not knowing better. They then need to get some ashes quickly to put in the grill so Al doesn't find out. Kelly finds an Urn at the neighbors and pours the cremated remains into the BBQ, not realizing what they are, just that they're ash. etc etc
