What do you mean funny, funny how? How am I funny?
People are funny sometimes.
Not, "Haha, do I look like a clown to you?" funny, but rather in a hypothesis-generating, "Why do people act the way they do?" funny. There are times where these are the same, and depending on your perspective, the following examples I present could be both. Regardless, people's actions never cease to astound me, as does the ignorance of their own behavior.
Even if we can never figure out why people do the things they do, there are some things about which we can be certain. One of these is that cell phones have fundamentally changed our social protocols and created an illusion of self importance. Now, that's funny.
