In 1975, a new sitcom set in a Brooklyn high school came to television, called Welcome Back, Kotter. Gabe Kaplan played Mr. Kotter, a teacher trying to reach a group of underachieving students known as the "Sweathogs." The adventures and schemes of students Vinnie Barbarino, "Boom Boom" Washington, Arnold Horshack and Juan Epstein proved endearing and hilarious, and Gabe Kaplan's Mr. Kotter was America's favorite TV teacher in the late '70s. 

Kaplan's portrayal of Mr. Kotter hit just the right notes -- he was endlessly relatable. Kotter's students got it, and so did the real people watching their TVs at home. Kotter wasn't the kind of teacher who'd get you into Harvard, but if you were in trouble or in danger of failing in life, he was the teacher who could save you. And he did it in a way that his students could understand; he wasn't trying to be their best friend, but he was a lot friendlier than the authority figures who'd written them off. Many young people watching the show, remedial and straight-A students alike, saw in Mr. Kotter the sort of classroom leader they wished they had.

The Sweathogs were students in the remedial class of the fictional James Buchanan High School, in the Bensonhurst neighborhood of Brooklyn, New York. Each of the main characters had his own special niche and stood out for it. All the students were lacking in some way or another but generally the one thing they all had in common was that they were a little bit lazy. They only attended school because they had to, and prided themselves on getting by with doing as little as possible. Fortunately, or unfortunately, depending on how you look at it, their teacher, Mr. Kotter, had their number, as he was a former remedial student himself -- in fact, he was one of the original Sweathogs.
