Three women Scientists. A Brunette, a RedHead, and a Blonde.
They were discussing where in space to travel next.
The Brunette states that Mars should be the next planet.
The Redhead suggested Saturn.
The Blonde suggest the Sun.
The other two look at her with astonishment and say, "you can't
go to the Sun, one would burn up".
The blonde replies "Duh, not if you go at night".
