Problem: Background: Steven Frederic Seagal was born in Lansing, Michigan on April 10, 1952, the son of medical technician Patricia (1930-2003) and high school math teacher Samuel Seagal (1928-1991). His mother was of Dutch, English, and German ancestry, while his paternal grandparents were Russian Jews who immigrated to the U.S. He also has Irish and Mongolian heritage. When Seagal was five years old, his parents relocated to Fullerton, California.
Context: Seagal moved to Japan at some point between 1971 and 1973. The date of his journey has become a point of contention due to Seagal's statement that he studied with Morihei Uyeshiba, the founder of aikido, who died in 1969. Terry Dobson, a fifth-degree black belt who studied with the master from 1961 to 1969, dismissed this claim, saying, "That story is bull. [Back then] I never heard of Steven Seagal." By 1974 Seagal had returned California. That year he met Miyako Fujitani, a second-degree black belt and daughter of an Osaka aikido master who had come to Los Angeles to teach aikido. When Miyako returned to Osaka, Seagal went with her. The following year they married and had a son, Kentaro, and a daughter, Ayako. He taught at the school owned by Miyako's family (though he is often stated to have been the first non-Asian to open a dojo in Japan). As of 1990, Miyako and her brother still taught there, and her mother was the chairwoman.  Seagal initially returned to Taos, New Mexico, with his student (and later film stuntman) Craig Dunn, where they opened a dojo, although Seagal spent much of his time pursuing other ventures. After another period in Japan, Seagal returned to the U.S. in 1983 with senior student Haruo Matsuoka. They opened an aikido dojo, initially in North Hollywood, California, but later moved it to the city of West Hollywood. Seagal left Matsuoka in charge of the dojo, which he ran until the two parted ways in 1997.  Seagal helped train Brazilian Mixed Martial Artist Lyoto Machida, who credited Seagal for helping him perfect the front kick that he used to knock out Randy Couture at UFC 129 in May 2011.
Question: What significance did martial arts have in his life?
Answer: The date of his journey has become a point of contention due to Seagal's statement that he studied with Morihei Uyeshiba, the founder of aikido, who died in 1969.

Problem: Background: 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.
Context: 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.
Question: How many were there?
Answer:
Future Jackass castmember Wee-Man made an appearance in the videos as well.
