Imagine transcription: An image of Light Yagami, Misa Amane, and L from Death Note on a fiery background. The caption reads: "Did you know, in the anime 'Death Note' for copyright reasons, the milk has to be spelt 'MLK' on the cartons? Google 'MLK Death Note' to find out more!". End transcription.

I've looked around but can't find anything. Source?
Surely with it being a Japanese anime, the milk containers wouldn't have English text on them but rather be in Japanese - which might make it harder for me to Google to find an article discussing it, as it's probably not written up in English.
