After finishing their studies the last year students put on some funny costumes and go around the city to throw candy to younger students. The seniors also arrange the "morning radio" in Halikon lukio. They usually make fun of the teachers and other students. The seniors also give the school a whole new decoration: they put trash bags and funny pictures of the younger students on the walls of the school. The second year students will give diplomas to the seniors. After that the seniors will go for a truck ride around the city.
