Integrating PHP into the workplace

Hello, I recently started a new part time job. It's a web development job. The company runs off of ALL NT or 2000 boxen. I've been friends with the CEO for quite a while, and have asked him many times when he's going to start using some open source apps. He always laughs at me. And the other day, I told my supervisor that php could solve a certain problem she was having. Today, I ran into another problem that php could have handled that regular HTML can't. My questions is, how should I go about getting that company to use SOME open source? Their scripting language of choice right now is ASP. I'm sure somebody has dealt with this type of thing before.
