Context: Hogan remained WWF World Heavyweight Champion for four years (1,474 days). In front of 33 million viewers, however, Hogan finally lost the title to Andre on the February 5 episode of The Main Event after a convoluted scam involving "The Million Dollar Man" Ted DiBiase and Earl Hebner (who assumed the place of his twin brother Dave Hebner, the match's appointed referee). After Andre delivered a belly to belly suplex on Hogan, Hebner counted the pin while Hogan's left shoulder was clearly off the mat. After the match, Andre handed the title over to DiBiase to complete their business deal. As a result, the WWF World Heavyweight Championship was vacated for the first time in its 25-year history because then WWF President Jack Tunney decreed the championship could not be sold from one wrestler to another. At WrestleMania IV, Hogan participated in a tournament for the vacant WWF World Heavyweight Championship to regain it; he and Andre were given a bye into quarter-finals, but their match resulted in a double disqualification. Later that night in the main event, Hogan came to ringside to stop Andre interfering which helped "Macho Man" Randy Savage defeat Ted DiBiase to win the title.  Together, Hogan, Savage, and manager Miss Elizabeth formed a partnership known as The Mega Powers. After Savage became WWF World Heavyweight Champion at WrestleMania IV, they feuded with The Mega Bucks (Andre the Giant and Ted DiBiase) and defeated them at the main event of the first SummerSlam. They then went on to feud with Slick's Twin Towers: Akeem and Big Boss Man.  In mid-1988, Hogan wrestled at house shows in singles competition with his "War Bonnet", a red and yellow gladiator helmet with a fist-shaped crest. This was notably used to give Bad News Brown his first WWF loss at a Madison Square Garden house show before it was discarded altogether. The War Bonnet gimmick was revisited in the WWE's online comedy series Are You Serious? in 2012.  The Mega Powers began to implode due to Savage's burgeoning jealousy of Hogan and his paranoid suspicions that Hogan and Elizabeth were more than friends. At the Royal Rumble in 1989, Hogan eliminated Savage from the Royal Rumble match while eliminating Bad News Brown, which caused tension, only to be eliminated by The Twin Towers himself. In early 1989, the duo broke up while wrestling The Twin Towers on the February 3 episode of The Main Event, when Savage accidentally collided with Miss Elizabeth during the match, and Hogan took her backstage to receive medical attention, temporarily abandoning Savage, who slapped Hogan and left the ring, where Hogan eventually won the match by himself. After the match, Savage attacked Hogan backstage, which started a feud between the two. Their feud culminated in Hogan beating Savage for his second WWF World Heavyweight Championship at WrestleMania V.
Question: what did they do together?
Answer: they feuded with The Mega Bucks (Andre the Giant and Ted DiBiase) and defeated them at the main event of the first SummerSlam.

Background: Murray Newton Rothbard (; March 2, 1926 - January 7, 1995) was an American heterodox economist of the Austrian School, a historian, and a political theorist whose writings and personal influence played a seminal role in the development of modern right-libertarianism. Rothbard was the founder and leading theoretician of anarcho-capitalism, a staunch advocate of historical revisionism, and a central figure in the twentieth-century American libertarian movement.
Context: Murray Rothbard's parents were David and Rae Rothbard, Jewish immigrants to the U.S. from Poland and Russia, respectively. David Rothbard was a chemist. Murray attended Birch Wathen, a private school in New York City. Rothbard later stated that he much preferred Birch Wathen to the "debasing and egalitarian public school system" he had previously attended in the Bronx.  Rothbard wrote of having grown up as a "right-winger" (adherent of the "Old Right") among friends and neighbors who were "communists or fellow-travelers." Rothbard characterized his immigrant father as an individualist who embraced the American values of minimal government, free enterprise, private property, and "a determination to rise by one's own merits". "[A]ll socialism seemed to me monstrously coercive and abhorrent."  He attended Columbia University, where he received a Bachelor of Arts degree in mathematics in 1945 and, eleven years later, his PhD in economics in 1956. The delay in receiving his PhD was due in part to conflict with his advisor, Joseph Dorfman, and in part to Arthur Burns rejecting his doctoral dissertation. Burns was a longtime friend of the Rothbard family and their neighbor at their Manhattan apartment building. It was only after Burns went on leave from the Columbia faculty to head President Eisenhower's Council of Economic Advisors that Rothbard's thesis was accepted and he received his doctorate. Rothbard later stated that all of his fellow students there were extreme leftists and that he was one of only two Republicans on the Columbia campus at the time.  During the 1940s Rothbard became acquainted with Frank Chodorov and read widely in libertarian-oriented works by Albert Jay Nock, Garet Garrett, Isabel Paterson, H. L. Mencken and others, as well as Austrian economist Ludwig von Mises. In the early 1950s, when Mises was teaching at the Wall Street division of New York University Business School, Rothbard attended Mises' unofficial seminar. Rothbard was greatly influenced by Mises' book, Human Action. Rothbard attracted the attention of the William Volker Fund, a group that provided financial backing to promote various "right-wing" ideologies in the 1950s and early 1960s. The Volker Fund paid Rothbard to write a textbook to explain Human Action in a form which could be used to introduce college undergraduates to Mises' views; a sample chapter he wrote on money and credit won Mises's approval. For ten years, Rothbard was paid a retainer by the Volker Fund, which designated him a "senior analyst." As Rothbard continued his work, he enlarged the project. The result was Rothbard's book Man, Economy, and State, published in 1962. Upon its publication, Mises praised Rothbard's work effusively.
