Once again this below list is not original with me. I received it via the e-mail social networks on the Internet. There is no way to identify author or provide attribution. I post it here for your amusement. For Chinese scholatrs studying in the West the percentage of puns in this list you understand and appreciate is an indication of your English and general western culture knowledge. My personal opinion is that if you appreciate half of this list without help, you are very good indeed.
