Problem: Background: Celebrity Rehab with Dr. Drew, later called simply Rehab with Dr. Drew, is a reality television show that aired on the cable network VH1 in which many of the episodes chronicle a group of well-known people as they are treated for alcohol and drug addiction by Dr. Drew Pinsky and his staff at the Pasadena Recovery Center in Pasadena, California. The first five seasons of the series, on which Pinsky also serves as executive producer, cast celebrities struggling with addiction, with the first season premiering on January 10, 2008, and the fifth airing in 2011. The sixth season, which filmed in early 2012, featured non-celebrities as treatment subjects, and the series name shortened to Rehab with Dr. Drew. Season 6 premiered on September 16, 2012.
Context: According to a December 2009 New York Times article, Drew Pinsky, who was alarmed by tabloid portrayals of addiction as an indulgence of the rich and famous, and a group of independent producers, approached VH1 with a proposal for a reality television series which would authentically depict addiction, as a sort of media intervention. According to executive producer John Irwin, casting for the first season was the most difficult, as the representatives of the celebrities who had been arrested or had publicized bouts with addiction refused to speak with him and the other producers. The process became easier after the first season aired. Actor Tom Sizemore, for example, who was cast for Season 3, had been sought after since Season 1. Producers have reportedly offered actress Lindsay Lohan six figures to appear on the show. Pinsky, who focuses on the treatment side of the production, is not usually involved with casting, though he reportedly visited Rachel Uchitel personally in order to convince her to join the fourth-season cast.  A multitude of cameras are employed, which film twenty-four hours a day, seven days a week, during the 21-day treatment cycle. Because some dramatic incidents occur early in the morning when the camera crews are not present, automated cameras are mounted all over the clinic to capture them. The exception to this are the bathrooms, which nonetheless are equipped with microphones to monitor unusual sounds, such as patients attempting to use drugs. In addition to receiving the free treatment (which would normally be worth approximately US$50,000-60,000), the patients receive a salary for their appearance on the series, which is prorated, and distributed once a week as an incentive to stay. Celebrity Rehab spun off two other shows. The first spinoff is Sober House, which depicts Rehab alumni living for 30 days at a sober living facility, as an interim step for recovering addicts between the completion of rehab and their eventual return to their old life. The second spinoff is Sex Rehab with Dr. Drew, in which Pinsky and his staff treat celebrities for sexual addiction.  In May 2013, Pinsky announced that season six was the final season, citing the criticism leveled at him following the relapse and death of cast members, saying, "I'm tired of taking all the heat. It's very stressful and very intense for me. To have people questioning my motives and taking aim at me because people get sick and die because they have a life-threatening disease, and I take the blame? Rodney King has a heart attack and I take blame for that? It's just ridiculous." Pinsky insisted that his practices depicted on the show were the same ones he, Bob Forrest and Shelly Sprague engaged in for decades, with the sole difference being the presence of cameras. Despite his decision not to continue the series, Pinsky stated a number of people achieved sobriety due to Celebrity Rehab who would not have attained it without the show, and cites as the biggest success story Sizemore, who struggled with Pinsky's program for 10 years before finally achieving sobriety after being on the show.

Background: Kevin Jeffrey Clash (born September 17, 1960) is an American puppeteer, director and producer whose characters include Elmo, Clifford, Benny Rabbit, and Hoots the Owl. Clash developed an interest in puppetry at an early age and began performing for local TV children's shows in his hometown of Baltimore, Maryland, as a teenager. In the early 1980s, he began working in Captain Kangaroo and began performing in Sesame Street in 1984. He was the fifth puppeteer to perform Elmo, the character he became the most famous for and became an executive producer and director for the show.
Context: Kevin Clash was born in Baltimore, Maryland, on September 17, 1960, the third of four children born to George Clash, a flash welder and handyman, and Gladys Clash, who ran a small daycare center in their two-bedroom, one-bath home in the Turner Station of Dundalk, Maryland. Clash developed an interest in puppetry at an early age, inspired by children's shows like Kukla, Fran and Ollie and Sesame Street. He made his first puppet, a version of Mickey Mouse, at the age of 10. When he was twelve, he created a monkey puppet out of the lining of his father's coat. His first performances were for his mother's daycare children.  By the time he was a teenager, he had built almost 90 puppets, which he based upon commercials, popular music, and his friends. While still in high school, Clash performed at venues throughout Baltimore, including schools, churches, fundraisers, and community events. While appearing at a neighborhood festival, Clash was discovered by Baltimore television personality Stu Kerr, who became Clash's first mentor and hired him to perform in the children's show Caboose at Channel 2. Clash also built puppets for the Romper Room franchise. When he was 17, he contacted and met puppeteer Kermit Love, who became Clash's mentor, after seeing Love featured in an episode of the documentary Call It Macaroni. In 1979, on Love's recommendation, Clash appeared as Cookie Monster in the Sesame Street float during the Macy's Thanksgiving Day Parade, and met Jim Henson, who later became his boss, mentor, and good friend.  When he was nineteen, Clash became a puppeteer for Captain Kangaroo, initially as a guest performer, in which he also made occasional on-camera appearances. The producers of Captain Kangaroo used some of Clash's puppet creations for the show. In 1984, Clash had to turn down Henson's offer to work on his film The Dark Crystal because he was working on two TV shows at the same time, Captain Kangaroo and Love's syndicated program The Great Space Coaster, in which he was producer for the first time.
