In "King for a Day, Part 2," Zedd and company enjoy watching Jason fighting off a brainwashed Tommy. They anticipate "the Rangers finally out of the way"... only to realize that would gain them nothing, as the Machine Empire would be able to conquer Earth unimpeded. This leads Zedd to declare - much to his disbelief and difficulty - there's only one thing they can do:
Zedd: (seething) We have to...help the Power Rangers! (shudders)
Also in that episode, there's the "fight scene" pitting Bulk and Skull against a squad of Cogs. Suprisingly, Bulk and Skull actually win the fight when their usual bumbling somehow translates into a fair amount of inadvertent, yet hilariously effective Deadly Dodging.
"Another Song and Dance". Morphing call. The best part is that while Nakia Burrise does have an excellent singing voice, Jason David Frank... doesn't (although, according to some sources, Frank's singing voice is good, he just thought it'd be funnier for Tommy to be hilariously off-key.)
Y'know what? The entire episode itself is hilarious, since we get both Tanya and Tommy being forced to sing all their dialogue after a monster afflicts the two with a spell that causes them to sing non-stop. Even their morphing callsigns are redubbed in their singing voices for this episode. We also get the Megazords being forced to dance thanks to the aforementioned spell. Which is hilariously awesome.
The Rangers defeating Cogs by pieing them. Especially at the end. All the Cogs except one teleport away. The straggler asks "Hey, where'd they go?" and then gets hit by a pie from each Ranger.
Something about Zedd's line when Rita gets them approval to crash in Master Vile's galaxy while the Machine Empire invades Earth is hilarious.
Zedd: Goodie goodie gumdrops...
Zedd's peace offering to the Machine Empire includes giving young Prince Sprocket a present; at this point, Zedd has stolen a page out of Jokey Smurf's playbook...
Zedd: (driving away in the camper) I hope they get a bang out of our going-away present...(chuckles)
In "A Zeo Beginning, Part II", the Rangers are bombarding Zordon and Alpha with questions about the Machine Empire, and Alpha tries to stop them, but suffers a meltdown and ends up shooting sparks out of the little "bump" on his head and babbling:
Alpha: Too many questions, must process all information- (babbling noises)
