anybody have any advice on getting adsense to to display more revelant ads?

Some Videos Show Good revelent ads but many show completely irrelevent. Eg. Video Called hammerguy shows links to Hammers and tools.

I am getting a ton of traffic but because of the irrelevent adsense ads I am not getting the amount of clicks that I should.

If we could change the URL to contain more relevent keywords that would be good.
