I think that's an excellent question and I'm interested to hear what other people think. I'm the kind of person who picks up languages for fun, so I learn a new language pretty fast. So, I'm usually willing to say I have "experience" in a language I've dabbled in (and done a couple projects solely for the purpose of learning the language); if I need the language for the job, I know I'll be able to handle it just fine thanks to Google. A CV with a million niche languages on it looks ridiculous, however, so I try to tailor the list to what I think would look good to whoever's reading it: enough languages that it looks impressive, but not so many that they question whether it's possible or not. I would only recommend doing this if you have sufficient programming experience and a firm enough grasp of fundamentals to be able to pick up new things quickly, however. Also, this assumes that you know enough about the language that you can discuss it intelligently.
