Anime References/Easter eggs

Thought this would make for a cool thread, have you guys ever caught any references in other shows/anime? If so where?

 

HotshotGG is in Zettai Karen Children: The Unlimited - Hyoubu Kyousuke

 

Jojo references are probably the most notable, they r fking everywhere lol.

Kimi no na Wa was referenced in a Tenki no Ko ad. Was pretty cool since both movies came from the same writer.
