"Mr. Tinkertrain" is the first song on the 1991 Ozzy Osbourne heavy metal album No More Tears. The single peaked at number 34 on Billboard's Album Rock Tracks chart.

Its lyrics are about child abuse, loss of virginity through rape, and pedophilia, sung from the point-of-view of the perpetrator rather than the victim.

The song begins with a stock sound clip of children playing together. The same clip can also be heard in the movie Sometimes They Come Back as well as the Season 2 finale of Boardwalk Empire. The introduction is suddenly interrupted with a heavily distorted guitar, before Ozzy delivers the line "Would you like some sweeties, little girl?", a line stereotypically associated with child kidnappers.

As the song progresses the unknown child is invited into a "palace full of fantasy," with "the kind of toys you've never seen, man-made and a bit obscene!"

The chorus of the song involves Ozzy telling his victim to "come along and play my game," telling her "you'll never be the same." This is likely a reference to the loss of the girl's virginity and her resulting mental scarring.

Mister, usually written in its abbreviated form Mr or Mr. (American English), is a commonly used English honorific for men under the rank of knighthood. The title derived from master, as the equivalent female titles, Mrs., Miss, and Ms, all derived from the archaic mistress. The title master was retained and used for boys and young men, but is now less commonly used. The plural form is Misters, or the abbreviation Messrs (UK) or Messrs. (US) ( /ˈmɛsərz/). This is an English abbreviation of the French "messieurs" (French pronunciation: [mesjø]), sometimes pronounced /ˈmɛsərz/ in English.

When addressing someone directly: Mr. is usually used with the last name only ("May I help you, Mr. Thompson?"). In other circumstances, it can be used with either the last name or the full name ("This is Mr. John Smith."; "Would you please help, Mr Smith?"). In formal written address, it is usually used along with the full name, or with initials and surname.

When a man's name is unknown, "mister" is sometimes used informally by itself in direct address, as in, "Hello, mister," or "Are you all right, mister?" rather than the standard form of address, "Sir". Though not necessarily meant disrespectfully, such use may to some people seem rude.

John Michael "Ozzy" Osbourne (born 3 December 1948) is an English heavy metal vocalist and songwriter, whose musical career has spanned over 40 years. Osbourne rose to prominence as lead singer of the pioneering English band Black Sabbath, whose dark and hard sound helped spawn the heavy metal genre. Due to Sabbath's dark style, Osbourne became known as the "Prince of Darkness". Osbourne is also known as the "Godfather of Heavy Metal".

In the early 2000s, Osbourne's career expanded when he became a star in his own reality show The Osbournes, alongside wife/manager Sharon and two of their three children, Kelly and Jack. A documentary about his life and career, God Bless Ozzy Osbourne, premiered in April 2011 at the Tribeca Film Festival and was released on DVD in November 2011. Osbourne has achieved multi-platinum status as a solo artist and with Black Sabbath and has sold over 100 million albums worldwide.

John Michael "Ozzy" Osbourne was born in Aston, Birmingham, England, on 3 December 1948. His father Jack worked shifts as a toolmaker at GEC. His mother Lillian worked for the car components firm Lucas. John was the fourth of six children. Ozzy had two brothers (Paul and Tony) and three sisters (Jean, Iris and Gillian); they lived in a small two bedroom home at 14 Lodge Road in Aston. The nickname "Ozzy" was first used when he was in primary school. Although called "John" by his first wife Thelma, Osbourne states that it has been a long time since he's recognised himself when called by his formal name.

Zachary Phillip "Zakk" Wylde (born Jeffrey Phillip Wielandt, January 14, 1967), is an American musician, songwriter, and occasional actor who is best known as the former guitarist for Ozzy Osbourne and founder of the heavy metal band Black Label Society. He was the lead guitarist and vocalist in Pride & Glory, who released one self-titled album in 1994 before disbanding. As a solo artist he released Book of Shadows in 1996.

Wylde was born in Bayonne, New Jersey. Wylde started playing the guitar at the age of 14 and worked at Silverton Music in Silverton, New Jersey. He grew up in Jackson, New Jersey, and went to Jackson Memorial High School, where he graduated in 1985. Wylde has stated that he would practice playing the guitar as much as 12 hours per day and would often play the guitar almost non-stop between coming home from school and leaving for school the next morning, then sleeping through the school day.

Wylde played locally with his first band Stone Henge, then later with local Jersey band Zyris. Later, he landed the role as lead guitarist and co-writer for Ozzy Osbourne. He sent Ozzy a demo tape in 1987 and was hired to replace Jake E. Lee, who had replaced the deceased Randy Rhoads. Rhoads remains Wylde's foremost guitar-playing and stagecraft influence.
