The Great "Dale" Misunderstanding

According to Mary Jo Pehl, in a May 14, 1997 online chat: "Dale is the daughter of a woman who a guy thought was Dale cuz her hands were so soft in an old TV commercial." Kevin Murphy echoed this idea. Unfortunately, the writers were mixing up two different commercials.

"Dale" actually appeared in a "Grape-Nuts" cereal commercial, where a boy, who is swimming in a pool with his girlfriend Dale Burke and her mom, says, "Oh, no -- Mrs. Burke! I thought you were Dale!" Mrs. Burke goes on to explain how many people confuse her with Dale because she stays young eating Grape-Nuts, blah, blah.

There *was* a hand-soap (or possibly dish-detergent) commercial in which someone mistakes a mother for her daughter, just as Mary Jo said, but it didn't include Dale. That's right -- they only thought it was Dale!
