The Sweathogs definitely did not suffer from a lack of merchandizing. They appear here as bendy figures on skateboards from 1977. These were produced by Gabriel and were released alongside Mickey, Donald, and Goofy. I picked these up recently as a lot of 3 and unfortunately I'm missing Vinnie Barbarino. Horshack, Juan Epstein and Freddie "Boom Boom" Washington are still a pretty sweet skate crew. I'm too young to have watched Welcome Back, Kotter during its original run but I did watch it when was picked up by Nick at Nite in the mid-'90s.
