Ernest Kador Jr. (February 22, 1933 – July 5, 2001), known by the stage name Ernie K-Doe, was an African-American rhythm-and-blues singer best known for his 1961 hit single "Mother-in-Law", which went to number 1 on the Billboard pop chart in the U. S. Born in New Orleans, K-Doe recorded as a member of the group the Blue Diamonds in 1954 before making his first solo recordings the following year. "Mother-in-Law", written by Allen Toussaint, was his first hit, reaching number 1 on both the Billboard pop chart and the Billboard R&B chart.

K-Doe never had another top-40 pop hit, but "Te-Ta-Te-Ta-Ta" (number 21, 1961) and "Later for Tomorrow" (number 37, 1967) reached the R&B top 40. In the 1980s K-Doe did radio shows on the New Orleans community stations WWOZ and WTUL.

The shows were known for his explosively energetic announcements and frequent self-promotion (occasionally causing problems for the noncommercial station). K-Doe's catch phrases included "Burn, K-Doe, Burn!

", "I'm a Charity Hospital Baby! " and (addressed to himself) "You just good, that's all!

". For a time he billed himself as "Mister Naugahyde", until he was ordered to desist by the owners of the Naugahyde trademark.

K-Doe then explained that it was a misunderstanding; he was actually referring to himself as "Mister M-Nauga-Ma-Hyde", a word he invented himself. In the 1990s K-Doe began billing himself as "The Emperor of the Universe" and, wearing a cape and crown, became a famous local eccentric in New Orleans.

He continued performing and occasionally recording until shortly before his death. Always an elaborate showman, one of K-Doe's most notable later performances was at the Aquarium of the Americas, in New Orleans, where he performed at a benefit for a local group aiding people with disabilities.

The show ended with K-Doe performing seven continuous renditions of "Mother In Law" while dancing in front of the Gulf of Mexico shark tank exhibit dressed in a green plumed cape. Later recordings of note include "White Boy, Black Boy".

While best known as a singer, he was also an accomplished drummer. The song "Here Come the Girls" was released in 1970 in England, but was not a hit.

It was re-released in 2007 as a result of its use in an advertising campaign for Boots stores and reached number 43. A cover by the Sugababes reached number 3 on the UK charts in 2008.
