From the second episode, Four's a Crowd. Ayeka's worrying about Tenchi and Ryoko trolls her by imagining all kinds of horrible stuff that could happen.
Ryoko: Poor Tenchi, he was hit by a car on his way to school this morning.
(Ayeka freaks out imagining Tenchi being struck down by a car with an angry expression)
Ryoko: After that he was kidnapped by video pirates.
Ayeka (imagining Tenchi with bloodshot eyes staring at a TV): Oh my!
Ryoko: It's possible he was picked up by a vicious woman-!
Ayeka: He's just not interested in another relationship!
Ryoko: I forgot, you're vicious enough for anyone.
From the third episode, Long Distance Lunacy, Washu's system of keeping an eye on Tenchi gets corrupted, so by the time any information about Tenchi arrives it's hopelessly warped. One such message "Tenchi's moving a very large piece of furniture up the stairs of his school." became "A hippo and a cow are about to push Tenchi over a cliff." The girls are immediately horrified, but Ayeka had this to ask:
Ayeka: Where did he find a hippo in Japan?!
In an earlier part of the episode, the scene of Ryoko and Ayeka as they watch Tenchi in the locker room. Ayeka covers Ryoko's eyes, then scopesTenchiout for herself!
Ryoko's rather deadpan response to learning this episode's monster is the guardian spirit of cell phones and cordless devices.
Ryoko: There's a spirit for everything.
In episode 4 "The Eternal Pledge", Ayeka, Ryoko and Hotsuma get into a fight. After Hotsuma's attack, Tenchi convinces Sakuya that Ayeka and Ryoko are Ghostbusters. It doesn't take long for her to become their biggest fan.
The episode 12, "Stupid Cupid" gives us Nobuyuki's duplicate. Which grabs Sakuya and charges through the streets bellowing that he is in love with her. And poor Sakuya is of course completely baffled.
He actually does this to every woman he spots while running around to the point that while he's asking the newest lady to "be his" she tells him (understandably) that she's not available. Her little daughter then calls the duplicate an idiot, but in the English Dub...
The start of episode 10 "Ryoko's Big Date". Has Ryoko applying makeup to her face by the pound, so she ends up resembling The Joker. The initial sight of her has everyone recoiling in terror, and then laughing their heads off once they realize it's Ryoko and what she's done. Ayeka gets the most pleasure out of this; she's bawling her eyes out from laughing so hard!
Episode 13, Kiyone and Mihoshi's reaction to Yugi's attack on the Misaki family. As she fires lightning bolts at them while they run for their lives.
Kiyone: (to Mishoshi) You didn't steal a lollipop from some kid who turned out to be a demon did you?
Mihoshi: Course not, I took some kids' ice cream but that was a long time ago!
Episode 18, Kiyone's joy while fantasizing about getting a promotion. It's rather bizarre when Mishoshi appears to be the sane one by comparison.
Mihoshi: (while crying) Ohhh! Kiyone is totally losing her mind!
Episode 19 "The Lonely Princess", Ayeka attempting to force open the door to Washu's laboratory with a mallet. When that inevitably fails, she attempts to force it open again. With a bigger mallet.
Episode 20, Ryoko putting Mishoshi and Kiyone through hell with crazy chores when she discovers they'd infiltrated her pirate gang. Including cleaning out the dungeon, laundry and cooking for the entire gang.
Ryoko: Hahaha! Hope you can barbeque, were carnivores. (a dinosaur appears from behind a huge door, ready to eat the girls) By the way, so is the main dish.
Episode 21 "Real Friends?", Sakuya's underwhelmed reaction to Washu popping up out of Tenchi's toilet thanks to a screwup with her dimensional portal.
Sakuya: (perfectly calm) I know her. How come she ended up in your toilet?
