What's "joke" mean here? I thought it has a positive connotation.

A joke on its own is a funny, good thing, because its meant to be humorous and entertaining. Being called a joke, however, is not a good thing. To be a joke means to be considered inadequate, worthy of ridicule, or a laughing stock. It's a good thing to tell a joke, but not to be one! You can also use "joke" to refer to things that are ridiculous or inadequate. Ex: This whole class is a joke. The teacher doesn't bother to help us when we have questions. Ex: I was upset because my friend called me a joke.
