"Whose picture is on a Susan B. Anthony dollar?" "I have no idea." "How much is a Susan B. Anthony dollar worth?" "I don't know, ten dollars?" "Is there such a thing as a two dollar bill?" "Yes, I have a couple, actually. Is that how much that Susan B. Anthony dollar is worth?" "You said ten dollars ... so how many two dollar bills would it take to equal a Susan B. Anthony dollar?" "Four, yeah, four." I paraphrased from having heard it just now without my transcription tablet handy, but that was the gist. Leno and his Jaywalking segments always seem to get quite a laugh. I personally never find riffraff imbecility very amusing, actually rather frightening instead.
