Dr. Lincoln in Operation: S.U.P.P.O.R.T

"Well well, if it isn't my oldest daughter. What are you, oh PU, we better operate immediately girl!"
-- Dr. Lincoln

Dr. Lincoln is the father of Numbuh 5, Cree and Junior Lincoln. Like most adults, he seems pretty oblivious to the KND's goings-on. He thinks his two daughters, Numbuh 5 and Cree Lincoln get along well, unaware of their deep rivalry.


Before he became a doctor, it is revealed he used to be a clown as seen in a flashback in Operation: C.L.O.W.N.. He was friends with a fellow clown named Bonko, but after Bonko failed to deliver a punch line at a birthday party and got clobbered by the kids at the party, Lincoln decided that being a clown was stupid and got a real job as a doctor. He reunited with Bonko at a circus and after discussing why he never went back to being a clown, he got jobs for Bonko and his gang jobs at the hospital he works at. He and Bonko decided to deliver one last joke for old times' sake: the chicken crossing the road joke. But like before, Bonko failed to deliver the punch line and got clobbered by the audience at the circus.


  • His face is never shown throughout the series, but his mouth is shown in Operation: S.U.P.P.O.R.T. and Operation: C.L.O.W.N..
  • It's revealed that he is a grandfather at a very young age due to him having a son who has children of his own.
  • He is an obvious parody of Bill Cosby's The Cosby Show character, Dr. Huxtable, due to him being a doctor, wearing sweaters, and having similar mannerisms in his speech. 
  • He is voiced by Kevin Michael Richardson throughout the episodes he appeared.
