Says the Pot to the Kettle, "Why you gotta metal?"

"That's the Pot Calling the Kettle Black"

OK, now I know where this phrase comes from. I mean I don't know who said it first, but I do understand what it means. However, I also feel that is has become slightly outdated.

Both pots and kettles come in different colors now, so shouldn't the phrase be updated to something like, "that's the Red Cephalon pot calling the polka dotted kettle black?" I am just saying, you should really be more specific in this day and age otherwise it is just a generic statement that is describing the appearance of two things that look different while trying to say they look the same.

I also found this alternative version of the phrase:

"That's the pot bottom calling the kettle bottom black"

I would like to know who says this, as you need to turn down your stove top and stop burning your pans.

And then there is this version,
"pot, kettle, black"

I would also like to know who says this. As you are just lazy and stupid and need to start talking in full sentences.
