Egg and brains for breakfast. (Pork)
Dang, I wish I were going to a costume party tonight!
“DOCTOR”
From Merriam-Webster
Bolding mine.
Although definition indicates the plural is most often used for the figurative sense, I would say it would also be OK informally to refer to the brain tissue of a single person.
You can say, “My brain hurts” or you can say, “My brains hurt”.
You can’t say, “My brains hurts”.
Unless, of course, you are speaking lolcatz.

There it is.
Common, maybe, but grammatically incorrect. My sources, online dictionaries, say that the word “brains,” in the plural, generally means “intelligence” as in “he’s the brains of that outfit” or “lots of brains in that family.” As to your examples, you wouldn’t say “I shot his livers out” or “his pancreases were all over the place,” would you? You could correctly say “I blew his kidneys out.” One liver, one brain, two kidneys. But in your examples, one would conceivably be excused from using the more correct, “his brainage matter oozed onto the sidewalk,” for example.
Perhaps I should be using more smilies. Your use of “brains” like that is an idiom and is just fine. No one who hears you say that will be thinking you actually blew out more than one of his brains. I’m sure they will be preoccupied with other concerns at the time.
You obviously haven’t offended any of the Grammer Nazies on this board.
Just watch. 
I dunno. I think it’s pretty weirds.
There are no pain receptors in the brain. So you can’t say anything of the sort.
Reality is for those who can’t handle dope!
I don’t know why the word should take a plural form in English when it’s singular in other languages-- although it’s interesting that in Finnish the word for brain is *aivot *which has the plural -*t *ending and is declined according to the plural noun declension, just like in English… except that there is no singular form of this word, anomalously.
I don’t know why it isn’t plural. The brain looks plural.
See!
