Aloysius Snuffleupagus, more commonly known as Mr. Snuffleupagus or Snuffy, is one of the characters on the educational television program for young children, Sesame Street. He was created as a woolly mammoth, without tusks or (visible) ears, and has a long thick pointed tail, similar in shape to that of a dinosaur or other reptile. He has long thick brown hair and a nose, or "snuffle", that drags along the ground. He is a friend of Big Bird and has a baby sister named Alice. He also attends Snufflegarten.

For many years, Big Bird was the only character on the show who saw Mr. Snuffleupagus, but later in the 17th season (1985) he showed his friends on Sesame Street his "imaginary" friend so they believe him. Mr Snuffleupagus also had a weird habit of watching the other characters while they sleep. This made him seem frighting and creepy to children so the episode when this was revealed was never aired on television. Before that happened, the main adult characters teased Big Bird when he said he had seen the Snuffleupagus, because they did not believe there was such an animal, often despite evidence to the contrary (such as an oversized teddy bear that Snuffy had left behind, or segments in which Snuffy interacted with other characters, such as a street scene where Snuffy was seen playing London Bridge with some of the neighborhood kids). This concept was meant to echo the existence of imaginary friends some young children have.^{[citation needed]} The Snuffleupagus' fur in the earlier years was light brown as it is today, but not exactly the same shade; he also had yellow almond-shaped eyes with thin pupils and shorter eyelashes. This appearance was deemed frightening for younger children, so later it was revamped to have his eyes look normal and to have a friendly personality.

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.
