"Is this thing on?" has to rank as possibly the 2nd greatest protest board slogan (after the one in my icon, of course)
I really liked "Magnets: How the **** do they work?"
This made me snork my coffee.
Well, that made my day. Thanks!
My fave? "God hates Jedi" -- held by someone in a STrek uniform.
Nice choice of icon with the post, too.
