The photo shows a screen of a Turkish TV channel with a red banner that says "17 YILDIR HİÇ MUTLU OLMADI" (It hasn't been happy for 17 years) and below it it says "TÜRKİYE 5 MİLLETVEKİLİ BULUNAN 'İYİ PARTİ' MECLİSİN 5. PARTİSİ" (Turkey's 5th party in parliament, the 'Good Party', with 5 MPs). The joke is that the "Good Party" has been in parliament for 17 years, which is a long time, but it has never been able to form a government or achieve any major political success. Therefore, it's implied that the party has never been happy with its political position.
