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!"
