I watched Don Phillips, the commercial announcer, out of the corner of my eye. The camera in front of me swung around and lined up on my set.

“ ... And now, on with the show,” Phillips was saying. “And here, ready to test your wits, is your quizzing quiz master, Smiling Jim Parsons.”

I smiled into the camera and waited while the audience applauded. The camera tally light went on and the stage manager brought his arm down and pointed at me.

“Good afternoon,” I said into the camera, “here we go again with another half hour of fun and prizes on television’s newest, most exciting, game, ‘Parlor Quiz.’ In a moment I’ll introduce you to our first contestant. But first here is a special message to you mothers...”

The baby powder commercial appeared on the monitor and I walked over to the next set. They had the first contestant lined up for me. I smiled and took her card from the floor man. She was a middle-aged woman with a faded print dress and old-style shoes. I never saw the contestants until we were on the air. They were screened before the show by the staff. They usually tried to pick contestants who would make good show material--an odd name or occupation--or somebody with twenty kids. Something of that nature.

I looked at the card for the tip off. “Mrs. Freda Dunny,” the card said. “Ask her where she comes from.”

I smiled at the contestant again and took her by the hand. The tally light went on again and I grinned into the camera.

“Well, now, we’re all set to go ... and our first contestant today is this charming little lady right here beside me. Mrs. Freda Dunny.” I looked at the card. “How are you, Mrs. Dunny?”

“Fine! Just fine.”

“All set to answer a lot of questions and win a lot of prizes?”

“Oh, I’ll win all right,” said Mrs. Dunny, smiling around at the audience.

The audience tittered a bit at the remark. I looked at the card again.

“Where are you from, Mrs. Dunny?”

“Mars!” said Mrs. Dunny.

“Mars!” I laughed, anticipating the answer. “Mars, Montana? Mars, Peru?”

“No, Mars! Up there,” she said, pointing up in the air. “The planet Mars. The fourth planet out from the sun.”

My assistant looked unhappy.

I smiled again, wondering what the gag was. I decided to play along.

“Well, well,” I said, “all the way from Mars, eh? And how long have you been on Earth, Mrs. Dunny?”

“Oh, about thirty or forty years. I’ve been here nearly all my life. Came here when I was a wee bit of a girl.”

“Well,” I said, “you’re practically an Earthwoman by now, aren’t you?” The audience laughed. “Do you plan on going back someday or have you made up your mind to stay here on Earth for the rest of your days?”

“Oh, I’m just here for the invasion,” said Mrs. Dunny. “When that’s over I’ll probably go back home again.”

“The invasion?”

“Yes, the invasion of Earth. As soon as enough of us are here we’ll get started.”

“You mean there are others here, too?”

“Oh, yes, there are several million of us here in the United States already--and more are on the way.”

“There are only about a hundred and seventy million people in the United States, Mrs. Dunny,” I said. “If there are several million Martians among us, one out of every hundred would have to be a Martian.”

“One out of every ten!” said Mrs. Dunny. “That’s what the boss said just the other day. ‘We’re getting pretty close to the number we need to take over Earth.’”

“What do you need?” I asked. “One to one? One Martian for every Earthman?”

“Oh, no,” said Mrs. Dunny, “one Martian is worth ten Earthmen. The only reason we’re waiting is we don’t want any trouble.”

“You don’t look any different from us Earth people, Mrs. Dunny. How does one tell the difference between a Martian and an Earthman when one sees one?”

“Oh, we don’t look any different,” said Mrs. Dunny. “Some of the kids don’t even know they’re Martians. Most mothers don’t tell their children until they’re grown-up. And there are other children who are never told because they just don’t develop their full powers.”
