Welcome Back, Kotter

Gabe Kotter returns to his old high school -- this time as a teacher. He's put in charge of a class full of unruly remedial students called the Sweathogs. They're a bunch of wisecracking, underachieving and incorrigible students, and it takes all of Mr. Kotter's humor -- and experience as a former Sweathog himself -- to deal with his class.
