Monkey Punch: Manga Katsudou Daishashin

Both are Monkey Punch's works, and have the same feeling to them. The Lupin characters appear many times in the Mankatsu shorts. 

If you're into comedic series that are nothing but a couple of separate short stories per episode, both series are a must. A fair word of warning though, as they also both contain some pretty suggestive humor, Mankatsu more so than Gag Manga Biyori. However, if you liked the one, you're surely gonna enjoy the other.  

Made by the same people and have lots of similar ideas: style of animation, plot lines, atmosphere, sense of humor and etc. In every mankatsu series there are short parts abut Lupin and his friends. If You liked Mankatsu watch Lupin the III movies, specials, OVAs and tv series, if you like Lupin watch Mankatsu. You wont regret. 

It's a comedy that makes fun of various stereotypes concerning Japan and Japanese.
