Lips

A boss had an interview with 4 girls for a secretary position. He asked the same question to each of them:

Boss: A woman, normally has lips in different places. What is the difference?

1st girl: One is hairy, the another isn't.
Boss: OK. Good!

2nd girl: One can talk, the another can't.
Boss: That's better.

3rd girl: One is vertical, the another is horizone.
Boss: You are clever.

4th girl: One for me, the another is for my boss.
Boss: You are hired.
