We've all probably met someone like this, that developer who just knows that his language is the one true language and won't shut up about it. How do you deal like someone like this? I don't want to offend anyone (especially since the fanboy in my workplace is the senior developer). But I want to be able to use my own choice of scripting language when I have to write a throwaway script that never makes it to the repository and no one else need know existed.

Thoughts that I had to dealing with this:

1. Laugh it off - "Haha yeah maybe language X is a bit easier, I guess I'm a masochist!"
2. Go with it - I'd really prefer to avoid this as I can't afford the drop in productivity associated with picking up a new language.
3. Hide my language - Become a closet programmer and hide my monitor whenever I'm scripting or automating something.

What would you suggest for this situation?
