Pass the buck and get a receipt. Act at discretion, hey? Well that's exactly what I'm going to do, and I kid you not.\nIt was later popularized by Jack Paar, host of The Tonight Show from 1957 to 1962, who used this as his signature phrase. It humorously combines the colloquial verb kid with the archaic negation through not without do-support.",
