Some context: Bernhard was born Bernhard Leopold Friedrich Eberhard Julius Kurt Karl Gottfried Peter, Count of Biesterfeld in Jena, Saxe-Weimar-Eisenach, German Empire on 29 June 1911, the elder son of Prince Bernhard of Lippe and his wife, Armgard von Cramm. He was a grandson of Ernest, Count of Lippe-Biesterfeld, who was regent of the Principality of Lippe until 1904. He was also a nephew of the principality's last sovereign Leopold IV, Prince of Lippe.
Prince Bernhard was a member of the "Reiter-SS", a mounted unit of the SS and joined the Nazi party. He later also joined the National Socialist Motor Corps.  Various members of his family and friends were aligned with the Nazis prior to the Second World War, a number of whom attended the royal wedding. Protocol demanded that the prospective Prince-Consort be invited to an audience with his head of state, who at the time was Adolf Hitler. Hitler himself gives an account of the conversation he had with Bernhard in his Tischgesprache (Table Conversations). Table Conversations was a collection of monologues, remarks, and speeches Hitler gave during lunch or dinner to those invited to the table by him. Bernhard himself called Hitler a tyrant in a public speech on the BBC on 25 June 1940 after France fell to Germany.  The Prince's brother, Prince Aschwin of Lippe-Biesterfeld, was an officer in the German Army. Although the secret services on both sides were interested in this peculiar pair of brothers, no improper contacts or leaks of information were ever discovered. The Prince proved himself to be a loyal Dutch citizen and officer. He cut off relations with those members of his family who were enthusiastic Nazis. As a sign of his "Dutchness" he spoke only Dutch when negotiating the surrender of German forces in the Netherlands. The Prince was known to be very fond of smart uniforms and medals. He made a point of wearing his medals in the English court style, even though members of the Dutch armed forces wear their medals in the Prussian style.  The Prince's mother was no admirer of the Nazis and got into trouble for refusing to hoist the swastika flag on her country seat at Reckenwalde.

Some context: Rowan & Martin's Laugh-In (often simply referred to as Laugh-In) is an American sketch comedy television program that ran for 140 episodes from January 22, 1968, to March 12, 1973, on the NBC television network. It was hosted by comedians Dan Rowan and Dick Martin. Laugh-In originally aired as a one-time special on September 9, 1967, and was such a success that it was brought back as a series, replacing The Man from U.N.C.L.E. on Mondays at 8 pm (ET). The title of the show was a play on the "love-ins" or "be-ins" of the 1960s hippie culture, terms that were, in turn, derived from "sit-ins", common in protests associated with civil rights and antiwar demonstrations of the time.
The first season featured some of the first music videos seen on network TV, with cast members appearing in films set to the music of the Nitty Gritty Dirt Band, the Bee Gees, the Temptations, the Strawberry Alarm Clock, and the First Edition.  During the September 16, 1968, episode, Richard Nixon, running for president, appeared for a few seconds with a disbelieving vocal inflection, asking "Sock it to me?" Nixon was not doused or assaulted. An invitation was extended to Nixon's opponent, Vice President Hubert Humphrey, but he declined. According to George Schlatter, the show's creator, "Humphrey later said that not doing it may have cost him the election", and "[Nixon] said the rest of his life that appearing on Laugh-In is what got him elected. And I believe that. And I've had to live with that." In an episode of the ill-fated 1977 revival, a Nixon impersonator says "I invited the American people to sock-it-to-me.... you can stop now".  On multiple occasions, producer George Schlatter attempted to get William F. Buckley Jr. to appear on the show, only to be refused each time until he suddenly agreed to an appearance. In the episode that aired December 28, 1970, Buckley appeared in an unusual sit-down segment (portions of which were scattered throughout the episode) flanked by Rowan and Martin and fielding questions from the cast (which included Lily Tomlin doing her Fast Talker shtick) and giving humorous answers to each. Near the end, when Rowan asked Buckley why he finally agreed to appear on the show, Buckley explained that Schlatter had written him "an irresistable letter" in which he promised to fly Buckley out to California "in an airplane with two right wings". At the end, Rowan thanked him for appearing, noting that "you can't be that smart without having a sense of humor, and you have a delightful one".
