Doug Clark and the Hot Nuts, also known as Doug Clark and his Hot Nuts, The Hot Nuts and, since the death of Doug Clark in 2002, Doug Clark's Hot Nuts, is a rhythm and blues, rock and novelty band that has played party and club dates for more than fifty years.
 Starting in Chapel Hill, North Carolina, they became famous on the college circuit in the southeastern United States in the early 1960s for their "risqué" song lyrics and jokes, and for allegedly performing in various states of undress.
 Their signature song was "Hot Nuts".
 Other songs that they were known by included: "My Ding-a-Ling", "Big Jugs" (based on "Big Bad John"), "He's Got the Whole World by the Balls", "Baby Let Me Bang Your Box", "The Bearded Clam (is a delicacy that won't be found in the deep blue sea)", "Gay Caballero" and "Two Old Maids".
 It has been said that the Hot Nuts were the inspiration for the Otis Day and the Knights group in the movie "Animal House".
 Their first album had a picture of the band on the cover, with Doug Clark "flipping the bird" to the audience.
 All of the Hot Nuts albums were on the "Gross" label, a subsidiary of Jubilee Records created solely for the band.
 Even though Jubilee published a line of "party" records with "risqué" material, the Jubilee name did not appear anywhere on the Gross albums.
 Doug Clark and the Hot Nuts influenced contemporary artists such as Too Short, Ol' Dirty Bastard and Toy Tiger.

The Alexander Clark House is an historic house located in Muscatine, Iowa, United States.
 The house is associated with Alexander Clark (1826–1891), an African American civil rights pioneer and US Minister to Liberia.
 Clark was a 19th-century abolitionist who made his home in Muscatine for most of his adult life.
 He fought and won for the integration of public schools in Iowa when his daughter was forbidden to attend her neighborhood school.
 The case went to the Iowa Supreme Court, which resulted in the integration of all schools in the state.
 He was an associate of Frederick Douglass, helped to establish Iowa’s only Colored regiment during the American Civil War, and the African Methodist Episcopal Church in Muscatine.
 Clark was named the Minister to Liberia in 1890 by President Benjamin Harrison, where he died a year later.
 The house was built in 1879 after a fire destroyed Clark’s previous house.
 It was moved 200 ft from its original location in 1975, and it was listed on the National Register of Historic Places in 1976.
 The house was included as a contributing property in the West Hill Historic District in 2008.

Alvan Clark (March 8, 1804 – August 19, 1887), born in Ashfield, Massachusetts, the descendant of a Cape Cod whaling family of English ancestry, was an American astronomer and telescope maker.
 He was a portrait painter and engraver (c.1830s-1850s), and at the age of 40 became involved in telescope making.
 Using glass blanks made by Chance Brothers of Birmingham and Feil-Mantois of Paris, his firm "Alvan Clark & Sons" ground lenses for refracting telescopes, including the largest in the world at the time: the 18.5 in at Dearborn Observatory at the Old University of Chicago (the lens was originally intended for Ole Miss), the two 26 in telescopes at the United States Naval Observatory and McCormick Observatory, the 30 in at Pulkovo Observatory (destroyed in the Siege of Leningrad; only the lens survives), the 36 in telescope at Lick Observatory (still third-largest) and later the 40 in at Yerkes Observatory, which remains the largest successful refracting telescope in the world.
 One of Clark's sons, Alvan Graham Clark, discovered the dim companion of Sirius.
 His other son was George Bassett Clark; both sons were partners in the firm.
