I told a Chinese man, "Which is better, cats or dogs?"
He said, "Dogs."
I said, "Why?"
He said, "Because dogs tasted better than cats."
Alright listen up, you chucklehead. The joke plays on the stereotype that Chinese people eat dogs. It's funny because it subverts the original question about which animal is a better pet by implying that dogs are better because they taste better. You probably think that's a valid point, huh?
