Well, the pot is calling the kettle black...!

The pot calls the kettle black

The U.S. pointing to China is a bit like the pot calling the kettle black. The deficit with China reflects poor policy on both sides of the Pacific.

Now that's a case of the pot calling the kettle metal.

In the beginning it was all black and white.

How agree the kettle and the earthen pot together? for if the one be smitten against the other, it shall be broken.
