A boss has to interview four girls for a job as his assistant. He asked the same question to each one of them.
Boss: A woman has lips in two different places on her body. What’s the difference between the two?
1st Girl: One is hairy, the other isn’t.
Boss: Ok, good.
2nd Girl: One can talk but the other can’t.
Boss: That’s better.
3rd Girl: One is vertical and other is horizontal.
Boss: Hmmmm…Very clever.
4th Girl: One is for me to use and the other is for my boss.
Boss: You are hired!
