Welcome Back, Kotter

Hey Julie....did I ever tell you about my Uncle Fremont Kotter.....?

Before Jerry Seinfeld wondered about airline peanuts, before Tim Allen said his first "Arrr arrr arrr!", before Roseanne became a Domestic Goddess, there was Gabriel Kaplan, the first stand-up comedian to successfully turn his comedy routines into a hit sitcom. Welcome Back, Kotter ran on ABC from 1975 to 1979.

Gabe Kotter, formerly a Sweathog, returns to James Buchanan High School as a teacher and is assigned the remedial class to which he once belonged. Mr. Kotter is an involved and caring teacher, which one would have to be in dealing with a certain four students in his class, who end up in trouble on a regular basis: ladies' man Vinnie Barbarino, the always cool Freddie "Boom-Boom" Washington, the tough Juan (Luis Pedro Phillipo de Huevos) Epstein, and the sheepish Arnold Dingfelder Horshack. Welcome Back, Kotter was based on Gabe Kaplan's own high school experiences with remedial education and a teacher who cared dearly for her students.

Changes on the show: Gabe Kaplan left the series in the third season, due to creative differences with executive producer James Komack. Kaplan openly felt that Komack was not serving the show's best interests. Kotter was made vice principal, and thus was seen considerably less. John Travolta (Creator), of course, found his own place as a celebrity, leaving the show around the same time Gabe Kaplan did (returning every so often as a "special guest star"). The replacement for Barbarino was Beau, who didn't help things much. By now the show had essentially lost its two biggest stars.

Welcome Back, Kotter contains examples of:

Epstein: I don't have to stay here and be ignored! I have nine brothers and sisters. If I want to be ignored, I'll just go home.
