3x7 - Sayonara Zetsubou Sensei

During a walk, Nozomu gets deceived by Maruuchi Shoko and Nedu Miko, who sell him maguro and a block of ice for 15.500 ¥. Nozomu complains that many dealers make up money only after the customers buy the goods, using tricks. The too mild winder is caused by Shogun Frost who refuses to do his work anymore. The class helps him to find a new job. The class prepares a surprise party for Nozomu, even if his birthday is not on that day, but on 4th of November.
