I hit him right between the nose

Wonderful mash-up of “right between the eyes” and “on the nose”, both referring to exactitude.  Facial features seem to be popular in malaphors….also expressions using animals.

You hit the nose on the head

If you type this malaphor on a google search, you get hundreds of responses, reflecting how often this malaphor is written/spoken.  It is a blend of “hit it on the nose” and “hit the nail on the head”, both phrases meaning getting something exactly right.  I suspect the confusion here is also prompted by two words that are both body parts and four letter words.   It also could be from watching too many Three Stooges comedies.
