These are just shorts for the main anime "Tanaka-kun wa Itsumo Kedaruge" which is also a very good anime worth watching. I liked these because they were random and funny, which is nice, but also entertaining. This little section of the anime series is something quick to watch after watching the main anime (12 episodes) the specials (7 episodes). Even though they are not as popular as the main anime probably, and the main anime is not very popular either, if you liked and watched the anime before, these are fun little episodes to watch as a little short continuation. These, by the way, areeach between around 20-30 seconds long. Will take you about maybe 1 22 min episode to watch all of them. Not long at all.

(My personal favorites, because they are funny, are episodes 13, 19, and 22. They are all about funny ideas to try and improve life)
