ドラえもんだらけ
ドラえもんだらけ ([i]Doraemon Darake[/i], "Full of Doraemon")

A famous episode from "volume 5":https://www.amazon.com/dp/4091400051/ of [[Doraemon]] manga, which involves [[Doraemon (character)|the titular character]] bringing four instances of his future self to help him doing the homework for [[Nobi Nobita]], only for it to ended up with him being beaten up by his future selves.

This episode is notable for displaying the concept of [[time paradox]], as the beaten-up Doraemon would be then brought back into the past by his past self every two hours while he's trying to rest, gradually increase his frustration and resulting into the "8-hour" Doraemon (the fourth copy of future Doraemon bought from 8 hours into the future) beating up his past counterpart.
