Sket Dance x Gintama

Hisashiburi minna~! It's been so long since i write the last post.  This time i'm gonna tell you about the crossover episode of Gintama and Sket Dance.  It's kinda unique for me that there is an anime episodes that really do crossover altough they are from different story and studios.
In this episode theres a character says about One Piece x Toriko (if i not mistake) because in Gintama .  The anime episodes is created based from the mangas chapter crossover in the both story.  In Sket Dance, this crossover is in chapter 180, but in Gintama this crossover is not  counted (special chapter).  Both Sorachi-sensei and Shinohara-sensei make these crossover manga chapters without checking each other and the content of the manga is overlapped each other (based on what Sorachi-sensei mentioned).  So, don't think Gintama x Sket Dance manga will have the same story as Sket Dance x Gintama.  Altough it's completely different story but it's still a good work, and you can find the "interesting" things in each manga.
