Anyone else remember the Lemon Popscile films? I loved watching them as a teenager. For anyone unaquainted they were teen films similar to Porky's but a lot funnier. As they were Israel/German made films they weren't very known over here at the time. There are 9 films in the series made between 1979 and 1987. They would even appeal to oldies as the stories centre around several teenagers growing up in the 1950s complete with music as the soundtrack from that period and with it filmed on location you really get a feel you're living the 1950s period.
Here's a tribute site for more information
