Chicken...crossing the road, of course

Robert De Niro:
Are you telling me the chicken crossed that road? Is that what you're telling me?

Martin Luther King, Jr:
I envision a world where all chickens, be they black or white or brown or red or speckled, will be free to cross roads without having their motives called into question.

Grandpa:
In my day, we didn't ask why the chicken crossed the road. Someone told us that the chicken crossed and that was good enough for us.

Captain James T Kirk:
To boldly go where no chicken has gone before.

Sigmund Freud:
The fact that you are at all concerned that the chicken crossed the road reveals your underlying sexual insecurity. How do you feel about your mother?

The C.I.A:
Who told you about the chicken? Did you see the chicken? There was no chicken. Please step into the car.

Albert Einstein:
Did the chicken really cross the road or did the road move beneath the chicken?

Bill Clinton:
I did not cross the road with THAT chicken. What do you mean by chicken? Could you define the word 'chicken'.

Homer Simpson:
Mmmm Chicken.
