"not know s.b from Adam""also Adam's off ox or from Adam's house cat"
[Definition]:Not know someone at all/Be unable to recognize someone
e.g: I wouldn't know my friend from Adam(meaning as follows)
meaning: you've never meet your friend and wouldn't recognize him if you did see him because he's a stranger to you (as is Adam). Even if you've dealt with him over the phone or by e-mail, you still wouldn't know him (from Adam) because you've never met him.
