Question:
Tool is an American rock band from Los Angeles, California. Formed in 1990, the group's line-up includes drummer Danny Carey, guitarist Adam Jones, and vocalist Maynard James Keenan. Justin Chancellor has been the band's bassist since 1995, replacing their original bassist Paul D'Amour. Tool has won three Grammy Awards, performed worldwide tours, and produced albums topping the charts in several countries.
The following year, at a time when alternative rock and grunge was at its height, Tool released their first full-length album, Undertow (1993). It expressed more diverse dynamics than Opiate and included songs the band had chosen not to publish on their previous release, when they had opted for a heavier sound. The band began touring again as planned, with an exception in May 1993. Tool was scheduled to play at the Garden Pavilion in Hollywood but learned at the last minute that the venue belonged to L. Ron Hubbard's Church of Scientology, which was perceived as a clash with "the band's ethics about how a person should not follow a belief system that constricts their development as a human being." Keenan "spent most of the show baa-ing like a sheep at the audience." Tool later played several concerts during the Lollapalooza festival tour, and were moved from the second stage to the main stage by their manager and the festival co-founder Ted Gardner. At the last concert of Lollapalooza in Tool's hometown Los Angeles, comedian Bill Hicks introduced the band. Hicks had become a friend of the band members and an influence on them after being mentioned in Undertow's liner notes. He jokingly asked the audience of 10,000 people to stand still and help him look for a lost contact lens. The boost in popularity gained from these concerts helped Undertow to be certified gold by the RIAA in September 1993 and to achieve platinum status in 1995, despite being sold with a censored album cover by distributors such as Wal-Mart. The single "Sober" became a hit single by March 1994 and won the band Billboard's "Best Video by a New Artist" award for the accompanying stop motion music video. With the release of Tool's follow-up single "Prison Sex", the band again became the target of censorship. The song's lyrics and video dealt with child abuse, which sparked controversial reactions; Keenan's lyrics begin with: "It took so long to remember just what happened. I was so young and vestal then, you know it hurt me, but I'm breathing so I guess I'm still alive ... I've got my hands bound and my head down and my eyes closed and my throat wide open." The video was created primarily by guitarist Adam Jones, who saw it as his "surrealistic interpretation" of the subject matter. And while some contemporary journalists praised the video and described the lyrics as "metaphoric", the American branch of MuchMusic asked Keenan to represent the band in a hearing. It deemed the music video too graphic and obscene, and MTV stopped airing it after a few showings. In September 1995, the band started writing and recording their second studio album. At that time Tool experienced its only lineup change to date, with bassist D'Amour leaving the band amicably to pursue other projects. Justin Chancellor, a member of former tourmates Peach, eventually replaced D'Amour, having been chosen over competitors such as Kyuss's Scott Reeder, Filter's Frank Cavanaugh, Pigmy Love Circus's E. Shepherd Stevenson, Jane's Addiction's Eric Avery and ZAUM's Marco Fox.

Answer the question at the end by quoting:

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.
Carson began his broadcasting career in 1950 at WOW radio and television in Omaha, Nebraska. Carson soon hosted a morning television program called The Squirrel's Nest. One of his routines involved interviewing pigeons on the roof of the local courthouse that would report on the political corruption they had seen. Carson supplemented his income by serving as master of ceremonies at local church dinners, attended by some of the same politicians and civic leaders whom he had lampooned on the radio. The wife of one of the Omaha political figures Carson spoofed owned stock in a radio station in Los Angeles, and in 1951 referred Carson to her brother, who was influential in the emerging television market in southern California. Carson joined CBS-owned Los Angeles television station KNXT. In 1953, comic Red Skelton--a fan of Carson's "cult success" low-budget sketch comedy show, Carson's Cellar (1951 to 1953) on KNXT--asked Carson to join his show as a writer. In 1954, Skelton during rehearsal accidentally knocked himself unconscious an hour before his live show began, and Carson successfully filled in for him. In 1955, Jack Benny invited Carson to appear on one of his programs during the opening and closing segments. Carson imitated Benny and claimed that Benny had copied his gestures. Benny predicted that Carson would have a successful career as a comedian. Carson hosted several shows besides Carson's Cellar, including the game show Earn Your Vacation (1954) and the CBS variety show The Johnny Carson Show (1955-1956). He was a guest panelist on the original To Tell the Truth starting in 1960, later becoming a regular panelist from 1961 until 1962. After the prime time The Johnny Carson Show failed, he moved to New York City to host Who Do You Trust? (1957-1962), formerly known as Do You Trust Your Wife?. In 1958, he appeared as a guest star in an episode entitled "Do You Trust Your Wife" on NBC's short-lived variety show, The Polly Bergen Show. On Who Do You Trust?, Carson met his future sidekick and straight man, Ed McMahon. Although he believed moving to daytime would hurt his career, Who Do You Trust? was a success. It was the first show where he could ad lib and interview guests, and because of Carson's on-camera wit, the show became "the hottest item on daytime television" during his five years at ABC.

Did he do anything at the same time as hosting shows?
He was a guest panelist on the original To Tell the Truth starting in 1960, later becoming a regular panelist from 1961 until 1962.
