Please Explain, Senator McCain

How does not knowing how many houses you & the beer baroness own have anything to do w/:

“Could I just mention to you, Jay, that, at a moment of seriousness,” McCain said, “I spent five-and-a-half years in a prison cell. I didn’t have a house. I didn’t have a kitchen table. I didn’t have a table. I didn’t have a chair. And I didn’t spend those five-and-a-half years because, not because I wanted to get a house when I got out."

It's like Rudy "The Catholic" Giuliani, except it's not "noun, verb, 9/11," it's "noun, verb, I was a POW for five-and-a-half years."
