BAKSTIRLA · HAVUZA · GİRMEK · YASAK
Yapay zeka açıklaması
The photo shows a sign that says "Bakstırla havuza girmek yasak." (It's forbidden to enter the pool with your back.)
The joke is that the sign is written in a way that suggests the person is actually trying to enter the pool with their back, not their front. This is humorous because it's a nonsensical way to enter a pool.
