Question:
John William Carson (October 23, 1925 - January 23, 2005) was an American television host, comedian, writer, and producer. He is best known as the host of The Tonight Show Starring Johnny Carson (1962-1992). Carson received six Emmy Awards, the Television Academy's 1980 Governor's Award, and a 1985 Peabody Award. He was inducted into the Television Academy Hall of Fame in 1987.
In 1973, magician, television personality, and self-proclaimed psychic Uri Geller appeared on The Tonight Show. In the NOVA documentary, James Randi - Secrets of the Psychics, magician and skeptical activist James Randi says that "Johnny had been a magician himself and was skeptical" of Geller's claimed paranormal powers, so prior to the date of taping, Randi was asked "to help prevent any trickery." Per Randi's advice, the show prepared their own props without informing Geller, and did not let Geller or his staff "anywhere near them." When Geller joined Carson on stage, he appeared surprised that he was not going to be interviewed, but instead was expected to display his abilities using the provided articles. Geller said "This scares me." and "I'm surprised because before this program your producer came and he read me at least 40 questions you were going to ask me." Geller was unable to display any paranormal abilities, saying "I don't feel strong" and he expressed his displeasure at feeling like he was being "pressed" to perform by Carson. According to Adam Higginbotham's Nov. 7, 2014 article in the New York Times: The result was a legendary immolation, in which Geller offered up flustered excuses to his host as his abilities failed him again and again. "I sat there for 22 minutes, humiliated," Geller told me, when I spoke to him in September. "I went back to my hotel, devastated. I was about to pack up the next day and go back to Tel Aviv. I thought, That's it -- I'm destroyed." However, this appearance on The Tonight Show, which Carson and Randi had orchestrated to debunk Geller's claimed abilities, backfired. According to Higginbotham, To Geller's astonishment, he was immediately booked on The Merv Griffin Show. He was on his way to becoming a paranormal superstar. "That Johnny Carson show made Uri Geller," Geller said. To an enthusiastically trusting public, his failure only made his gifts seem more real: If he were performing magic tricks, they would surely work every time.

Question:
Copeland was born in Orangeville, Ontario, the son of Judy Copeland, a single parent who worked two jobs to support her son. Copeland has stated that he has never met, nor ever seen a picture of, his father. He became interested in professional wrestling at a young age; his favorite wrestlers included Mr. Perfect, Randy Savage, Hulk Hogan, Ricky Steamboat, Shawn Michaels, and Bret Hart. As a teenager, Copeland attended WrestleMania VI sitting in the eleventh row at ringside.
Edge was placed on the Raw brand in the 2004 WWE draft lottery after WrestleMania XX and returned to in-ring action shortly after the event. At Backlash, Edge defeated Kane, and on the April 19, 2004 episode of Raw, he and World Heavyweight Champion Chris Benoit won the World Tag Team Championship. They continued a close partnership even after losing the title; at Bad Blood, Edge and Benoit defeated La Resistance in a Tag team match for the World Tag Team Championship by disqualification but didn't win the titles. The team disbanded when Edge won the Intercontinental Championship at Vengeance defeating Randy Orton, thus becoming a five time Intercontinental Champion. At SummerSlam, Edge defeated Chris Jericho and Batista in a Triple threat match to retain the WWE Intercontinental Championship. Following a legitimate groin injury in a non-televised match, Raw General Manager Eric Bischoff stripped Edge of the Intercontinental title. Upon his return, Edge began to show some heel characteristics centering on his obsession for the World Heavyweight Championship. Edge, Chris Benoit, and Shawn Michaels received a title shot for Triple H's World Heavyweight Championship at Taboo Tuesday in October 2004. Michaels won the audience vote to receive the title shot, giving Edge and Benoit a tag team title shot. During the match, an angry Edge abandoned his partner (although Benoit managed to win the title on his own) and instead interfered in the main event, costing Michaels the championship. On the November 1 episode of Raw, Edge and Benoit lost the World Tag Team Championship with Edge abandoning Benoit again and sitting in a chair and watching the match. After the conclusion of the match, Edge attacked Benoit, officially turning heel for the first time since 2001. Edge then adopted a drastically different gimmick, becoming a crazed and brash villain in the process. At Survivor Series, Edge was part of Team Triple H along with Triple H, Batista and Snitsky. They were defeated by Team Orton (Randy Orton, Chris Benoit, Chris Jericho and Maven). During the match, Edge eliminated both Chris Benoit and Chris Jericho before getting eliminated by Randy Orton. On the November 29 episode of Raw, both Edge and Benoit competed in a number one contender's battle royal, but they eliminated each other simultaneously at the conclusion of the match, resulting in a draw. As a result, Triple H was forced to defend the title in a triple threat match. In the match, Benoit locked the Crippler Crossface on Edge, who shifted his weight putting Benoit's shoulders on the mat for a pin. This match also ended in a draw for Benoit and Edge, as Benoit made Edge submit at the same time the referee counted a pinfall for Edge. As a result, the World Heavyweight title was vacated the following week on Raw. In January 2005, Edge competed in his first Elimination Chamber match at New Year's Revolution for the vacant World Heavyweight Championship. Shawn Michaels (acting as special guest referee) performed a superkick on Edge, in retaliation for an accidental spear by Edge, causing Edge to be the first eliminated. This led to a match at the Royal Rumble later in the month, in which Edge defeated Michaels.
