Non-stick pans aren't always...

I tried to make a cake today.  I used a "non-stick" bundt pan, that turned out to be anything but non-stick.  The cake tore in half, horizontally, and the part left in the pan disintegrated.  I tried to piece it back together and dumped frosting over it, which didn't work too well because the frosting kept trying to peel up the smaller cake chunks.
