A comment from my co-work about internet stories

Yesterday, after we discussed German nobles in this forum, it was time for me to go home. On the way to the parking lot, I told my co-worker, an American guy about the stories of someone married a rich German noble and someone dating a super rich guy, etc.

He said "Once I saw a funny cartoon, there were two dogs sat in front of a computer, one dog told another dog 'You know, people on the internet don't know that we are dogs'" I couldn't help to laugh.

P.S. Please don't get offended by this joke. After all, that is only a joke. It is just telling us that don't take the internet stories too serious.
