Who understands this joke? Tell me about it.

The story is based on common sense: "Once upon a time, there was a poor young man. I found a very big snail in the field, so I took it home happily. Going home the next day, the young man was surprised to find that the table was full of steaming food. " Anyone who knows here should have heard the fairy story of "Snail Girl", that is, the young man found a fairy. "Then the young neighbor came in with a bottle of wine:" You can come back and just help you cook snails. Let's have a good drink. "The second half is counterintuitive, with a turning point, adapted from the original story ~ I hope you can be satisfied with my answer.
