There was a young woman tossed up on a rocket
Ninety times as far as the moon.
Where was she going? I hastened to ask it
Before her vehicle started to zoom.
“Young woman, young woman, young woman,” I cried.
“Where are you going on your dangerous ride?”
“I’m headed to Mars,” was her joyful reply.
“Won’t you come with me?”
“No, not I!”
