What is a no-brainer?

Scott Hennen, WDAY: Would you agree a dunk in water is a no-brainer if it can save lives?
THE VICE PRESIDENT: It's a no-brainer for me, but for a while there, I was criticized as being the Vice President "for torture." We don't torture. That's not what we're involved in. We live up to our obligations in international treaties that we're party to and so forth. But the fact is, you can have a fairly robust interrogation program without torture, and we need to be able to do that. And thanks to the leadership of the President now, and the action of the Congress, we have that authority, and we are able to continue to program.

Next question, from me:
Would you agree the chained up current holder of the office of the Vice Presidency of the United States is a no-brainer?
Answer:
If that means someone without a brain (in the sense of something one employs to THINK), then the answer is an unequivocal YES.

Here's for some waterboards for Chainy and his entire chaingang!
