Hayato and Shiragiku are trying to come up with new menu items for fall. As they're discussing ideas with the neighborhood shop owners, the fishmonger brings up a memory of Hayato's grandma that he didn't know about...
For crying out loud! 
Would you stop being stupid?!
!يا إلهي! هلّا توقّفت عن هذا الغباء؟
Herrje! Rede doch nicht
die ganze Zeit so einen Unfug!
¡Santo cielo! ¿Cómo eres tan tonto?
¡Madre mía! ¿Cómo eres tan tonto?
Quel idiot ! Tu n’en as pas marre
de dire des sottises ?
Oh, cielo!
Pelo amor de Deus! Dá pra
parar de falar idiotices!?
Боже, когда ты уже
перестанешь глупости городить?
