I know some of you probably know headphones work as a microphone. I just learned this and I think its neat.

If you did not know give it a try. Plug in like your mp3 earbuds or try other headphones and get it close to your mouth and record through a audio recording program. It works descently, not as good as a real mic in quality or volume but it would work in case you forgot your mic and needed to have one.

I've tried, and it really works. And the quality is quite good! Thanks for the tip:)

how come mine doesn't work? i'm using a cellphone's earpluds

It seems to work best with small earbud type of headphones. Larger ones are more distorted...But earbuds work well...
