Did you laugh at the difference between a panda and a pig in a funny joke?

One day, my colleague and I discussed the difference between pandas and pigs. I said: pandas are cute and pigs are ugly, but my colleagues said: they are greedy and love to sleep. Why do people like pandas and hate pigs? I sighed and said, it's very important to look at your face these days.
