Will you star if you laugh?

Two sailors on shore leave, walking down the street. They spot a beautiful blonde.

First sailor asks his friend "Have you ever slept with a blonde?" Second sailor replies that he has.

They walk on further and see an even more beautiful brunette.

First Sailor: Have you ever slept with a brunette?"

Second Sailor" Why yes, in fact I've slept with brunettes on many occasions" They walk on a little further, and see a gorgeous redhead, who leaves the other two girls for dead.

First Sailor:" Have you ever slept with a redhead then?"

His companion looks at him and replies "Not a wink!"
