Episode 22 of Gurren Lagann, "That is my last duty". Why?
In that episode.
Shit.
Gets.
DONE.
Lemme tell it like it is; in that episode, Team Dai-Gurren is re-united after seven years, obtain a new ally in the form of at least two former enemies, achieve their first major victory against the Anti-Spirals, THIS happens in the meanwhile...
(Sorry, Frozen Donkey Wheel. The position of the best three minutes of your life has officially been taken over.)
What else? Oh yes. Moments after the events of that clip, they stop the Moon from going all Majora's Mask on the Earth, then they go inside the moon to TAKE CONTROL OF THE FREAKING MOON AND TURN IT INTO A MOTHERFUCKING BATTLESHIP.
Before he does that, however, the main character manages to get his girlfriend back. Y'know, just because she happened to be in the area.
To end things on a less anti-climactic note however, I'd like to say that this is also the episode in which the most hated character of the series realizes how big of an obstructive bellend he's been. It'll take too long to explain the details, so I'll just show you what it eventually leads up to in the next episode, when the main character decides to discuss the problem with him like a civillized gentleman.
GURREN FUCKING LAGANN, PEOPLE.
BEST.
ANIME.
EVER.
