Olaf the Viking Norseman is shopping at a supermarket when he comes across an old lady in a wheelchair, almost in tears.
"What's the matter?" asks Olaf.
"Oh," sobs the old lady. "I want to have a look at the frozen puddings but, as you can see, there are three steps down into the chiller cabinets."
"No problem," says Olaf, lifting her onto his back. "I'll take you."
Olaf strolls through the chiller cabinets with the old lady on his back. She selects several puddings and puts them in the basket he is carrying for her.
At the other end the old lady's husband is waiting with her wheelchair.
"I'd really like to thank you," says the old lady as Olaf sets her back down in the chair, "but I don't even know who you are!"
Olaf just waves and walks off.
"I was really worried about you," says the old lady's husband. "What have you been doing?"
She replies: "Well, I've been through the desserts on a Norse with no name."
