input: Beginning in May 2002, Jackson allowed a documentary film crew, led by British TV personality Martin Bashir, to follow him around nearly everywhere he went. On November 20 of that year, Jackson brought his infant son Prince onto the balcony of his room at the Hotel Adlon in Berlin as fans stood below, holding him in his right arm with a cloth loosely draped over Prince's face. Prince was briefly extended over a railing, four stories above ground level, prompting widespread criticism in the media. Jackson later apologized for the incident, calling it "a terrible mistake". Bashir's crew was with Jackson during this incident; the program was broadcast in March 2003 as Living with Michael Jackson. In a particularly controversial scene, Jackson was seen holding hands and discussing sleeping arrangements with a young boy.  As soon as the documentary aired, the Santa Barbara county attorney's office began a criminal investigation. After an initial probe from the LAPD and DCFS was conducted in February 2003, they had initially concluded that molestation allegations were "unfounded" at the time. After the young boy involved in the documentary and his mother had told investigators that Jackson had behaved improperly, Jackson was arrested in November 2003 and charged with seven counts of child molestation and two counts of administering an intoxicating agent in relation to the 13-year-old boy shown in the film. Jackson denied the allegations, saying the sleepovers were not sexual in nature. The People v. Jackson trial began on January 31, 2005, in Santa Maria, California, and lasted until the end of May. On June 13, 2005, Jackson was acquitted on all counts. After the trial, in a highly publicized relocation, he moved to the Persian Gulf island of Bahrain as a guest of Sheikh Abdullah. Unknown to Jackson, Bahrain was also where the family had intended to send Jackson if he had been convicted, according to a statement by Jermaine Jackson printed in The Times of London in September 2011.  On November 17, 2003, three days before Jackson's arrest, Sony released Number Ones, a compilation of Jackson's hits on CD and DVD. In the U.S., the album was certified triple platinum by the RIAA; in the UK it was certified six times platinum for shipments of at least 1.2 million units.

Question: Blanc was born in San Francisco, California to Russian-Jewish parents Frederick and Eva Blank, the younger of two children. He grew up in the neighborhood of Western Addition in San Francisco, and later in Portland, Oregon, where he attended Lincoln High School. Growing up, he had a fondness for voices and dialect which he began voicing at the age of 10. He claimed that he changed the spelling of his name when he was 16, from "Blank" to "Blanc", because a teacher told him that he would amount to nothing and be like his name, a "blank".

Blanc began his radio career at the age of 19 in 1927, when he made his acting debut on the KGW program The Hoot Owls, where his ability to provide voices for multiple characters first attracted attention. He moved to Los Angeles in 1932, where he met Estelle Rosenbaum (1909-2003), whom he married a year later, before returning to Portland. He moved to KEX in 1933 to produce and co-host his Cobweb and Nuts show with his wife Estelle, which debuted on June 15. The program played Monday through Saturday from 11:00 pm to midnight, and by the time the show ended two years later, it appeared from 10:30 pm to 11:00 pm.  With his wife's encouragement, Blanc returned to Los Angeles and joined Warner Bros.-owned KFWB in Hollywood in 1935. He joined The Johnny Murray Show, but the following year switched to CBS Radio and The Joe Penner Show.  Blanc was a regular on the NBC Red Network show The Jack Benny Program in various roles, including voicing Benny's Maxwell automobile (in desperate need of a tune-up), violin teacher Professor LeBlanc, Polly the Parrot, Benny's pet polar bear Carmichael, the tormented department store clerk, and the train announcer. The first role came from a mishap when the recording of the automobile's sounds failed to play on cue, prompting Blanc to take the microphone and improvise the sounds himself. The audience reacted so positively that Benny decided to dispense with the recording altogether and have Blanc continue in that role. One of Blanc's most memorable characters from Benny's radio (and later TV) programs was "Sy, the Little Mexican", who spoke one word at a time. The famous "Si ... Sy ... Sue ... sew" routine was so effective that no matter how many times it was performed, the laughter was always there, thanks to the comedic timing of Blanc and Benny. Blanc continued to work with him on radio until the series ended in 1955 and followed the program into television from Benny's 1950 debut episode through guest spots on NBC specials in the 1970s. They last appeared together on a Johnny Carson Tonight Show in January 1974. A few months later, Blanc spoke highly of Benny on a Tom Snyder Tomorrow show special aired the night of the comedian's death.  By 1946, Blanc appeared on over 15 radio programs in supporting roles. His success on The Jack Benny Program led to his own radio show on the CBS Radio Network, The Mel Blanc Show, which ran from September 3, 1946, to June 24, 1947. Blanc played himself as the hapless owner of a fix-it shop, as well as his young cousin Zookie.  Blanc also appeared on such other national radio programs as The Abbott and Costello Show, the Happy Postman on Burns and Allen, and as August Moon on Point Sublime. During World War II, he appeared as Private Sad Sack on various radio shows, including G.I. Journal. Blanc recorded a song titled "Big Bear Lake".
