Samurai Jack - Cartoon Network's Samurai Jack

Put that thing away Samurai. We all know what's going to happen: You'll swing your sword, I'll fly away, and say something like "I'll be back Samurai!", and I'll flutter off into the horizon, and we won't see each other for a week.
~Aku summing up the first four seasons

I started rewatching episodes, and I never noticed it as a kid, but like 50% of each episode is just looping clips over and over for a minute, like in a fight, it'll just be a 3 second loop of Jack swinging his sword for about 30 seconds.
