Gershon "Geri" Mandlebaum

Gershon "Geri" Mandlebaum (Yaniv Polishuk) is Koby's uncle and the owner/manager of the Hamburgery, an unsuccessful hamburger shop. He has 4 kids: Roni, his firstborn daughter and the troublemaker trio Shaike, Poli and Gavri (named after the "HaGashash HaHiver" comedy group). The trio is never seen in the show and so his wife Shifra (who always annoys Geri and described as fat and ugly woman). He hates his life and always says "Why?" after something bad happens to him. Geri and Shifra's niece, Dana, comes to help Geri in the hamburgeri's bussines troubles, but this makes even more angry. His daughter Roni always asks him for money (which he dosen't have), but sometimes also helps him. He has an enemy from his High-School (Hes in Petah-Tikwa), Shimon Tzimhoni, who hates him because he cut off the electricity in the parents' meeting. They ran for the mayor position in Season 3 (but none of them won). In Season 4 Geri get him into jail after he tried to buy the Hamburgeri and in Season 5 they fight again after Tzimhoni released from jail and opened a new hamburger shop called Tzimhoburger (hebrew for: veggieburger) near the Hamburgeri. He also deals with Oded, his worker in Hamburgeri, who is very stupid. He had a band with Oded Menashe, which was very successful, but after Badash became their agent, they split up.

He will appear in the show's next 2 seasons, which will air in September 2010.
