Jonathan Frink

Professor John I.Q. Neidelbaum Frink, Jr. is Springfield's main professor, and regularly appears in and around town.

Character information
Professor John Frink (referred to as Dr. Frink in the episode "Future-Drama") is generally depicted as Springfield's local stereotypical mad scientist. He has a trademark mannerism of using tourettes-like gibberish when excited, such as "GLAVIN!" and shouting other words that have no relevance to the situation at hand. He also occasionally refers to the importance of remembering to "carry the one" in various mathematical calculations. He is never seen without his glasses and almost never takes them off.

Frink is said to have an IQ of 197; 199 before he sustained a concussion during the collapse of Springfield's brief intellectual junta ("They Saved Lisa's Brain"). He is a member of the Springfield Mensa.

He holds an advanced degree in hyperbolic topology, mentioned in "Treehouse of Horror VI" when Homer gets trapped in the 3rd dimension. (This information could be considered non-canonical, as it appears in a TOH episode.)

He is a college professor at Springfield Heights Institute of Technology.

Frink is fond of flubber, a fictional material with enhanced bounce properties originating in the movie The Absent-Minded Professor. Professor Frink has basketball shoes made of flubber, as does Robin Williams in the 1997 Flubber movie.

He is also the inventor of, among other things, hamburger earmuffs and the 8-month after pill. Some of Frink's inventions, such as the automatic phone dialer, work better than others, such as his radio-controlled plane, which carries babies as passengers under their parents' control, or a secure house that sprouts legs and runs away from potential danger (the legs of which often collapsed causing the house to crash to the ground and catch fire). Frink has also discovered and cured "Frink's Disease" and discovered "Frinkonium." Professor Frink has also made many crazy inventions on the show, most notably on the Treehouse of Horror episodes, though these are generally not considered canon.

Professor Frink has not had a large role in the series, though he has been seen in many episodes. Professor Frink does not make any appearances in Season One and has only one speaking role in Season Two. However, in Season Three he has several speaking roles, and becomes a recurring character from then on. Professor Frink seems to know Lisa better than the rest of her family because she is more interested in science and makes more frequent visits to places such as the Natural History Museum and the Observatory.

Family
Frink had a strained relationship with his father (voiced by Jerry Lewis). Frink said they got along like "positrons and antineutrinos." The senior Professor Frink was a "he-man" scientist who, according to his son, worked on the atom bomb by day, slept with Marilyn Monroe by night, and sold secrets to the Russians at lunch. In "Treehouse of Horror XIV", Frink brought his father back to life, but he went on a rampage and younger Frink was forced to kick the elder in the nuts, killing him. It is indicated in this episode that their shared middle name is "Nerdelbaum". The two rebuild their relationship when the elder Frink is proud of his son for stopping him like a man, and said that he must now go to Hell. Frink managed to catch his father's soul with his newest invention the "Soul Catcher." Since Frink's father was seen in a Halloween episode, this information might be inaccurate, as it comes from a non-canon Halloween special.

Frink has a wife,though in later episodes they may be separated or divorced, and a young son who looks similar to him. Also in another episode "Brother, Can You Spare Two Dimes?" his son crashes through a window during a demonstration of a remote controled airplane, after this he says "my wife is going to kill me". But since his son is seen in later episodes sugesting that this is either a different son or that his son survived the accident. In The Simpsons Game, he marries a Koopa Troopa from Super Mario Bros., probably because The Simpsons Game parodies several video games.

Personal life
In "Future-Drama", an episode set eight years into a possible future of Bart and Lisa's, a bespectacled skeleton dressed in a lab coat is observed hanging on a rope from a rafter in Frink's basement laboratory—indicating the professor has committed suicide in the interim - although this could be a clone or his aforementioned son -, his death gone unnoticed by family and friends. However, another episode set further in the future, "Lisa's Wedding", shows him alive and well as he leads a team trying to discover the cure for seventeen stab wounds in Mr. Burns' back, stating "Well, we're up to fifteen!". Any successfull attempts to see into the future are most likely not canon.

At one moment in The Simpsons, Frink is commanded by a hypnotist to act desirable to women, whereupon Frink loses the glasses and frumpy appearance, and quickly becomes engaged with a nubile young waitress. However, the hypnotist shortly reverts Frink back to his usual nerdy self, with a quick snap of the fingers.

Frink: I don't wanna go back to the nothing!...Oh dear, I've re-dorkulated!

A similar event happens when Frink drinks Abraham Simpson's aphrodisiac tonic. Both events are references to Jerry Lewis' character from The Nutty Professor transforming into Buddy Love.

In the 1960s, Professor Frink made napalm to drop on Da Nang, according to "Homer's Paternity Coot." He once predicted that computers would be so large and so expensive that only the five richest kings of Europe would own them, a paraphrase of Thomas J. Watson's misquote. he has been featured in 139 episodes
