I am marginally aware that cats don't talk, though they can be extremely effective communicators. But I am currently completely addicted to lol cats, those funny pics of cats with humorous captions. If anyone hasn't seen this site and has a few days to spare...
One of their latest has a pic of an irritated looking cat with the caption, 'If you fell into a pond they would be skimming stupid off the surface for a week.'
I think that is such a good put down. I may memorise and steal.
