So many fans screaming at Justin all the time has affected the singer's memory.

During an interview in New Zealand, Justin was asked to answer a series of quick questions. The preguntas were really easy and he just had to basically say if they were true o false.

The host asked Justin if it was true that Bieber meant the same as 'basketball' in German. All Justin had to do was answer yes, no, o no idea. Instead, Justin asked what German was! How can he not know what German is?!

We're not sure if Justin is joking around o if he really has no idea what German is. If he doesn't then it is time for him to stop touring and head back to the libros at school.
