Right, and I took up Wild Bird Feeding this year as a hobby at Put-in-Bay, that has turned out to be a Squirrel feeding hobby instead.
I would outsmart them for a while, then they would invent a way to get to the seed and destroy the feeder.
So, I would come up with another way to stop them. after a couple of days, they figured out a way to get by that.

I felt like Elmer Fudd v. Bugs Bunny. <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />
At last, a place to vent.
