input: S. Samyro, a partial anagram of Samy Rosenstock, was used by Tzara from his debut and throughout the early 1910s. A number of undated writings, which he probably authored as early as 1913, bear the signature Tristan Ruia, and, in summer of 1915, he was signing his pieces with the name Tristan. In the 1960s, Rosenstock's collaborator and later rival Ion Vinea claimed that he was responsible for coining the Tzara part of his pseudonym in 1915. Vinea also stated that Tzara wanted to keep Tristan as his adopted first name, and that this choice had later attracted him the "infamous pun" Triste Ane Tzara (French for "Sad Donkey Tzara"). This version of events is uncertain, as manuscripts show that the writer may have already been using the full name, as well as the variations Tristan Tara and Tr. Tzara, in 1913-1914 (although there is a possibility that he was signing his texts long after committing them to paper). In 1972, art historian Serge Fauchereau, based on information received from Colomba, the wife of avant-garde poet Ilarie Voronca, recounted that Tzara himself had explained his chosen name was a pun in Romanian, trist in tara, meaning "sad in the country"; Colomba Voronca was also dismissing rumors that Tzara had selected Tristan as a tribute to poet Tristan Corbiere or to Richard Wagner's Tristan und Isolde opera. Samy Rosenstock legally adopted his new name in 1925, after filing a request with Romania's Ministry of the Interior. The French pronunciation of his name has become commonplace in Romania, where it replaces its more natural reading as tara ("the land", Romanian pronunciation: ['tsara]).

Question: Steve-O was born in the Wimbledon, London. His mother, Donna Gay (nee Wauthier), was Canadian, and his father, Richard Glover, was American. His paternal grandfather was English and his maternal step-grandfather was voice-over announcer Wayne Howell. His family was based in Brazil for many years due to his father's presidency of the South American division of Pepsi-Cola.

While performing in the flea market circus, Steve-O began sending videos of himself to Big Brother magazine editor and future Jackass director Jeff Tremaine. After admitting that the only thing he was scared of was spiders, Tremaine recruited Steve-O for MTV's television series Jackass, which became an instant hit. MTV has subsequently released five movies based on the series: Jackass: The Movie (2002), Jackass Number Two (2006), direct-home release Jackass 2.5 (2007), Jackass 3D (2010), and Jackass 3.5. The installments Jackass: The Movie, Jackass Number Two, Jackass 3D, and Jackass Presents: Bad Grandpa all became box office hits. In 2001, he released Don't Try This at Home on DVD, which contained material MTV censored. It went on to sell 140,000 copies. He toured promoting the DVD doing stunts, which was filmed and released as Don't Try This at Home Volume 2: The Tour. On July 31, 2002, Steve-O was arrested on obscenity and assault charges for stapling his scrotum to his leg, and for being a principal to a second-degree battery, during a performance at a nightclub in Houma, Louisiana on July 11, 2002. After several delays, in March 2003 Steve-O made a deal with Louisiana prosecutors placing him on supervised probation for one year, requiring him to make a charitable donation of $5,000 to a shelter for battered women and children and forbidding him from ever performing in Terrebonne Parish, Louisiana again. In 2003, Steve-O toured Europe with Bam Margera, a friend and co-star of Jackass. On May 22, 2003, Steve-O was arrested and jailed while in Sweden due to footage of himself swallowing a condom containing cannabis to get it past authorities while flying on a plane. He then regurgitated it live on stage, which he showed in his DVD Steve-O: Out on Bail (aka Don't Try This at Home - The Steve-O Video Vol. 3: Out on Bail) (2003). Steve-O reached a deal with the Swedish prosecutors and was released on May 27, 2003 after paying a 45,000 kronor (about 6,700 USD) fine. As part of the plea bargain Steve-O admitted to possessing one ecstasy tablet and five grams of marijuana, although he claimed he had no knowledge of where the ecstasy came from. The Swedish arrest was included in the third installment of the DVD series titled Steve-O: Out on Bail. Two months later on July 19, 2003, Steve-O was arrested on charges of disorderly conduct for urinating on potato chips in public during a Lollapalooza tour concert in Burgettstown, Pennsylvania. Steve-O claimed he was kicked off the tour by Lollapalooza producers because of the incident.
