A blond, a brunette, and a redhead were trying out for a new NASA experiment on sending women to different planets.
First, they called the brunette in and asked her a question.
"If you could go to any planet, what planet would you want to go to and why?" After pondering the question she answered, "I would like to go to Mars because it seems so interesting with all the recent news about possible extra terrestrial life on the planet." They said "well okay, thank you." And told her that they would get back to her.
Next, the redhead entered the room and the NASA people asked her the same question. In reply, "I would like to go to Saturn to see all of its rings." Again, "thank you" and they would get back to her.
Finally, the blond entered the room and they asked her the same question they asked the brunette and the redhead. She thought for a while and replied, "I would like to go to the sun."
The people from NASA replied, "why, don't you know that if you went to the sun you would burn to death?"
The blond smirked and put her hands on her hips. "Are you guys dumb? I'd go at night!"
