Is it heard where you live? What does it mean?
I know only 'as deaf as a post'.
Bill must live in a nicer part of the country than I do.
Dumb as post.
Dumb as a box of rocks.

I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
BrE has as thick as two short planks; also as thick as pigsh*t.
I live in Toronto. Where do you live?
By the way, I suspect that this idiom initially referred to deafness/dumbness, but with the evolution of meaning in the word dumb from speechless to stupid the meaning of the idiom also changed in an identical way.

I like "dumb as a sack of hammers."
And "dumb as a post" is a common phrase in American English so far as I know.
Having lived on both sides of the pond, I am aware of the regional nature of some idioms. But there are others that I hear, and I'm uncertain about how common they are in various places.
