There are at least 4 of these guys around Springfield...

Ya know, to me the Statue of Liberty is just absolutely the wrong icon to associate with your income tax. In fact, it does angry up my blood just a bit :) Lets see, the government confiscating your money before you even touch it and "Liberty". Nope, that strikes me as pretty oxymoronic association!
Now if these guys wanted to do this right they would have the Statue of Liberty whaling away on a guy in a three piece suit with a foam rubber baseball bat and the sign should say, "Let us help you beat back the tax man!"
Now THAT would work!
