How much money am I making from youtube?

youtube.com/cclown23

I just found out youtube has been putting ads on my videos, mostly on the one that got 150k views

I think they should be paying me for this type of stuff, but i dont have the slightest clue on how to collect my money (if i had made any) or how to contact youtube

Anyone?

Login to your adsense account, its probably the same as your youtube.
