I don’t know him from a hole in the wall

This is a mash up of “a hole in the wall” (obscure place) and “I wouldn’t know him from a hole in the ground” (obscure person).  Also in the mix has to be “doesn’t know him from Adam” and “he doesn’t know his ass from a hole in the ground”, as well as the visual of punching holes in the wall.   This blended idiom comes to us compliments of Barry Eigen, who heard it on yesterday’s (4/29/13) episode of The People’s Court, uttered by “Judge” Marilyn Milian.
