According to Frankfurt, bullshit is speech that doesn't show a proper concern for the truth. Lying, on the other hand, consists in thinking that one knows the truth and then saying something else.

I said we shouldn't shut the government down. (See from 2:30 to 3:45 in the video clip from The Daily Show below.)
Is this a lie or bullshit in the technical sense?
