.: Captcha Gotcha :.

Are you human?
I am asked when I log in.
I cannot believe it:
I am asked (I now can't leave it)
whether I am human!
Do I look like I'm alien?

Are you human? Not a computer?
To prove it, type the following words:
"One times one is three thirds!"
This sounds like a code,
a secret society mode,
according to some mantra of a replicant
from space's Gamma Quadrant.

I write those darn words
"One times one is three thirds!"
and you unlock for me.
If this were the proof, really,
that I am "humane,"
then my calculator is the same.
Thus you can't be any ruder;
for a calculator is much less than a computer!
