"Welcome Back, Kotter" was one of the funniest serials I have ever seen. It starred Gabe Kaplan as Mr. Kotter, who taught a remedial class of "Sweathogs" which featured Arnold Horshack, Juan Epstein, Freddie "Boom-Boom" Washington, and Vinnie Barbarino as four of his students. Between the hilarious plots and the identifiable high school situations, the show was a hit. What student in a diverse environment can't identify with "Roses are red, violets are blue, my mom wants me to date a Puerto Rican Jew"? My favourite episode focused upon the Sweathogs cleaning for a pregnant Mrs. Kotter, only to destroy her apartment. Reruns have been off the air in Canada for quite some time, so I suggest that if networks want to improve ratings, that they welcome back Kotter!
