Brain Game: Our Usual Punctuation Mark

Good luck with today’s Brain Game riddle!

These parts of our bodies
Are both large and small
They have only five letters
But you double them all.

What are they?

Here’s the SOLUTION.

  1. YES! I love feeling smart first thing in the morning =)

  2. And here I went for “pupil” because we have two eyes and you might have been making an old joke.

  3. “boobs” works too.

  4. They certainly work for me, Amanda. :X

  5. Wow! That was a good one. I didn’t get the solution, but when I saw it, I loved it. Awesome. This one’s getting shared on Google Reader.

  6. I went for “joint.”

  7. I went with teeth, thinking you have relatively large and small teeth, the word is five letters long, and with losing baby teeth as adult teeth come in, you double the number you have.

  8. I thought the clue in the title might give it away too… “our usual punctuation mark” in the title of our Brain Games is the colon. :)

    Good thing I didn’t go with my first choice, which was “Ailimentary, My Dear Watson…”

  9. I went for lungs. You have 2 and as you inhale and exhale they get bigger and smaller.

    But I guess they may not actually double in size, does anyone know the proportional difference between deflated and inflated lungs?

    PS, Matt I like your logic.

  10. Surprised at how quickly I got it, and impressed with the sheer genius at coming up with the riddle in the first place.

  11. I came up with “teeth,” too. With small baby ones and large adult ones, replacing one set with the other, I think it fits the clue just as well. You and me, Matt! Great minds think alike.

  12. Cells! OK, so they’re ALL small but not compared to each other — some are quite a bit larger. But they all double. :)

    And sure, CELL has just four letters, but it says THEY have five…and they do!
