user: Problem: Jackass is an American reality series, originally shown on MTV from 2000 to 2002, featuring people performing various dangerous, crude, self-injuring stunts and pranks. The show served as a launchpad for the television and acting careers of Johnny Knoxville, Bam Margera, and Steve-O, who previously had only minor acting roles. The show later sparked several spin-offs including Wildboyz, Viva La Bam, Homewrecker, Bam's Unholy Union, and Dr. Steve-O as well as three feature films distributed by MTV corporate sibling Paramount Pictures. Jackass sparked considerable amounts of controversy, as it was seen as indecent and encouraging of dangerous behavior.

The show developed from Big Brother Magazine, a skateboarding-related humor magazine that Jeff Tremaine, Dave Carnie, Rick Kosick and Chris Pontius all worked for, and featured regular contributions from Johnny Knoxville and Dave England, among others. The concept of Jackass dates back to 1998, when failing-actor-turned-writer Johnny Knoxville thought of the idea of testing different self-defense devices on himself as the basis for an article. He pitched the idea to a couple of magazines and was turned down until meeting with Jeff Tremaine of Big Brother. Tremaine hired him as a journalist and convinced Johnny to videotape this idea and other stunts for stories. The footage, which involved Knoxville being tasered, maced, and shot while wearing a bulletproof vest, appeared in the second Big Brother skateboarding movie: Number 2. Future Jackass castmember Wee-Man made an appearance in the videos as well.  During this time, Bam Margera released a movie titled Landspeed:CKY, consisting of himself and his friends, which he dubbed the "CKY Crew", in West Chester, Pennsylvania, performing various skits and stunts. The Crew included the colorful cast of Ryan Dunn, Brandon Dicamillo, and Raab Himself, as well as Margera's family April, Phil, Don Vito, and Jess Margera. Tremaine saw the tapes and drafted Margera and his crew into what would become the cast of Jackass. Later, the Jackass crew would recruit Steve-O in a Florida flea market where he worked as a clown. To round out the cast, England brought in his friend Ehren McGhehey, a fellow Oregon resident and extreme stunt participant. Preston Lacy would be the last of what is now considered the main cast to join, auditioning midway through the show's run by eating four bananas with the peels on.  Tremaine drafted his friend, director Spike Jonze, to get involved with the show, and together, he, Jonze, and Knoxville served as executive producers. The show idea was pitched, and the cast was initially given an offer by Saturday Night Live to perform the stunts weekly for the show, though the offer was turned down. A bidding war occurred between Comedy Central and MTV, which MTV eventually won. It was then that Jackass was born.

Problem: Chris Austin Hadfield  (born 29 August 1959) is a retired Canadian astronaut who was the first Canadian to walk in space. An engineer and former Royal Canadian Air Force fighter pilot, Hadfield has flown two space shuttle missions and served as commander of the International Space Station. Hadfield, who was raised on a farm in southern Ontario, was inspired as a child when he watched the Apollo 11 Moon landing on TV. He attended high school in Oakville and Milton and earned his glider pilot licence as a member of the Royal Canadian Air Cadets.

Hadfield was selected to become one of four new Canadian astronauts from a field of 5,330 applicants in June 1992. Three of those four (Dafydd Williams, Julie Payette and Hadfield) have flown in space. He was assigned by the Canadian Space Agency (CSA) to the NASA Johnson Space Center in Houston, Texas in August, where he addressed technical and safety issues for Shuttle Operations Development, contributed to the development of the glass shuttle cockpit, and supported shuttle launches at the Kennedy Space Center, in Florida. In addition, Hadfield was NASA's Chief CAPCOM, the voice of mission control to astronauts in orbit, for 25 space shuttle missions. From 1996 to 2000, he represented CSA astronauts and coordinated their activities as the Chief Astronaut for the CSA.  He was the Director of Operations for NASA at the Yuri Gagarin Cosmonauts Training Center (GCTC) in Star City, Russia from 2001 until 2003. Some of his duties included co-ordination and direction of all International Space Station crew activities in Russia, oversight of training and crew support staff, as well as policy negotiation with the Russian Space Program and other International Partners. He also trained and became fully qualified to be a flight engineer cosmonaut in the Soyuz TMA spacecraft, and to perform spacewalks in the Russian Orlan spacesuit.  Hadfield is a civilian CSA astronaut, having retired as a colonel from the Canadian Armed Forces in 2003 after 25 years of military service. He was Chief of Robotics for the NASA Astronaut Office at the Johnson Space Center in Houston, Texas from 2003-2006 and was Chief of International Space Station Operations from 2006-2008. In 2008 and 2009, he trained as a back-up to Robert Thirsk on the Expedition 21 mission. In May 2010, Hadfield served as the commander of the NEEMO 14 mission aboard the Aquarius underwater laboratory, living and working underwater for fourteen days. NASA announced in 2010 that Hadfield would become the first Canadian commander of the International Space Station, leading Expedition 35 after its launch on 19 December 2012. His craft docked with the station on 21 December. He remained on the station for five months, transferring control to Pavel Vinogradov and departing on 13 May 2013.  In June 2013, one month after completing his third trip to space, Hadfield announced his retirement from the Canadian Space Agency, effective 3 July 2013. Hadfield stated that after living primarily in the United States since the 1980s for his career, he would be moving back to Canada, "making good on a promise I made my wife nearly 30 years ago -- that yes, eventually, we would be moving back to Canada." He noted that he plans to pursue private interests outside government there.  Hadfield is enthusiastic about the prospects for a manned mission to Mars, and when asked in 2011 if he would consider a one-way journey to Mars to be the first to visit, he said "I would be honoured to be given the opportunity."
