Kimmel asked, “This is a question that I think is very important to me and very important to the country. When you were in office — and I don’t know when this happened or if it happened — did you go through the secret files; the UFO documents?”
The audience broke into laughter. Bush answered: "Maybe, I’m not telling you nothing."
So, the former President Bush is following the clever lines of the, then, president Obama, who had told Kimmel live, jokingly I might add: "The aliens won’t let it happen… they exercise strict control over us...I can’t reveal anything.”
Now, wouldn't it make sense for these guys to tell us something to lessen our interest in the subject if they could? I don't know, maybe something like, "There's nothing there!" Obviously, they don't gain anything from the vague answers.
As John Lennon once sang, "All I want is the true, just give me some truth... no short haired son...."
