Some context: 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.
On May 1, 1972, the show was moved from Thirty Rockefeller Plaza, New York, to Burbank, California, because of the studio's proximity to the celebrities. Carson often joked about "beautiful downtown Burbank" and referred to "beautiful downtown Bakersfield", which prompted Bakersfield Mayor Mary K. Shell to chide Carson and invite him to her city to see improvements made during the early 1980s.  From July 1971, Carson stopped hosting five shows per week. Instead, Mondays featured a guest host, leaving Carson to host the other four weeknights. Shows were videotaped in Burbank at 5:30 pm, fed from there to the Central and Eastern time zone stations via cross-country television line at 8:30 pm Pacific time (11:30 pm Eastern time), and later sent from Burbank to the Pacific time zone stations at 11:30 pm Pacific time. Since only two feeds originated from Burbank, Central time zone stations received the Eastern feed one hour earlier at 10:30 pm local time, and Mountain time stations received the Pacific time zone feed one hour later at 12:30 am local time.  In 1980, at Carson's request, the show cut its 90-minute format to 60 minutes on September 16; Tom Snyder's Tomorrow added a half-hour to fill the vacant time. Joan Rivers became the "permanent" guest host from September 1983 until 1986. The Tonight Show returned to using rotating guest hosts, including comic George Carlin. Jay Leno then became the exclusive guest host in fall 1987. Leno joked that although other guest hosts had upped their fees, he had kept his low, assuring himself more bookings. Eventually, Monday night was for Leno, Tuesday for The Best of Carson--rebroadcasts usually dating from a year earlier, but occasionally from the 1970s.  Although Carson's work schedule became more attenuated, Tonight remained so successful that his compensation from NBC continued to rise; by the mid-1970s, he had become the highest-paid personality on television, earning about $4 million a year ($15,008,000 today), not including nightclub appearances and his other businesses. He refused many offers to appear in films, including title roles in The Thomas Crown Affair and Gene Wilder's role in Blazing Saddles. He also declined director Martin Scorsese's offer to co-star with Robert De Niro in the 1983 film The King of Comedy, the role of a TV talk-show host then going to Jerry Lewis.  In recognition of his 25th anniversary on The Tonight Show, Carson received a personal Peabody Award, the board saying he had "become an American institution, a household word, [and] the most widely quoted American." They also said they "felt the time had come to recognize the contributions that Johnny has made to television, to humor, and to America."

Some context: Stewie Griffin: The Untold Story is a 2005 direct-to-DVD animated comedy film set in the Family Guy fictional universe. Released on September 27, 2005, the film's main plot point concerns Stewie Griffin trying to find who he thinks is his real father after seeing the man on TV. He travels to San Francisco, only to find that the man is him from the future.
When the Griffins go swimming at the Quahog Community Pool, Peter tries teaching Stewie to swim and attempts to toss him into the pool, despite Stewie begging to be put down. Lois takes Stewie to swimming lessons, where Stewie meets Brad, a child about his age who is the "Star Swimmer." In jealousy, Stewie does everything he can to steal Brad's glory. As a last resort he tries to kill him by rigging a lifeguard chair with dynamite and luring Brad beneath it with marzipan; however, Stewie's detonator malfunctions, blowing up the legs of chair and causing it to fall on Stewie himself. He ends up in hell with Steve Allen. When Stewie is revived by Lois, he believes it is a sign for him to be a good boy.  After Peter learns that the new video store will not let him rent pornography, he vents his frustration in front of newscaster Tom Tucker, who gives him a job at Quahog 5 hosting a segment called "What Really Grinds My Gears," in which he rants about things that bother him. Peter becomes extremely popular, overshadowing Tucker, who is fired after attempting to distract Peter during filming.  Stewie attempts to be a good boy by smothering Brian with affection. Brian finally goads Stewie into reverting to his old, violent ways by crushing a spider web and eating the spider. Stewie starts drinking heavily, following Brian's way of coping. Brian attempts to cure Stewie of his alcoholism by taking him out for a night of drinking at the Drunken Clam. While drunk, Stewie crashes Brian's car through the wall of the bar. Knowing Stewie is Peter's son, Tom takes advantage of the situation and presents footage of the accident at the news station. Peter is fired and Tom is rehired as the anchor. The next morning, Stewie has a hangover and realizes his lonely existence in the world, wishing that there were someone else to whom he could relate. At the end Stewie says it is good that he stopped drinking now, so that it would not have any repercussions later in life.
