In Cantonese, There are a lot of funny last name. for example, Zhou xin yu: 周新玉 its' sound is called 周身肉 Zhou shen rou。if it were called a girl that means her shape is full of meat. I think it is funny one.And 徐定富 is same, its sound is called 徐定裤。 that means taking off the pants. if you know Cantonese or Chinese, You will figure out what I say.
Have a nice day!
