Strange Stereotypes

Today my Dominican students told me a little joke that I was surprised to hear:

There are two buckets of crabs. One bucket has Chinese crabs and one bucket has crabs from the Dominican Republic. The bucket of Chinese crabs has a cover on it. The bucket of Dominican crabs doesn’t. Why?

The Chinese crabs will help each other escape from the bucket so the bucket needs a cover. The Dominican crabs will pull each other down so the cover isn’t necessary.

What do you think? Please post your comments.
