A blank click I wonder about it.

I saw it on my adsense report. I had two clicks with 0 payment. How could it be possible? There is a click and no money. Do you guys got this problem?

It can be invalid clicks, or Psa clicks perhaps...

5 for .09 cents here.

What's a PSA click anyway ?

Public Service Ad. It's what they display if no other ads are available.

Low/zero revenue from a click can be from "bad" countries (in the eyes of the advertisers). Russian traffic in particular often gets zero revenue because few advertisers target the Russian market as opposed to the US market where the same click will make you much more.
