This is the reason the internet was invented. I just didn't know it until now.
What we seem to have here is a group of kaiju, Japanese rubber-suited monsters, in a large group auditioning to "Billie Jean" in front of a panel of Ultramen. Just when you think it can't get any more ridiculous, they break into a perfect, synchronized "Thriller" dance. Words fail me. Pink Tentacle says its from the Japanese variety show called Mecha Mecha Iketeru!, but I first saw it on Twitter from user @Robogeek.
It has to be seen to be believed, and it's after the jump.
