We have just five words.. "Power Rangers" and Love Potion.
Cyber-Cam, when he's, you know, not evil and all.
"Sorry about the whole tying-you-up-in-the-closet thing."
Especially when he effectively curbstomps the rangers in their respective extreme sports.
There's also what is widely considered to be funniest moment in Power Rangers history. The first time the Thunder Rangers show up, it's during a battle with some Mooks. Dustin doesn't know who to fight, and Shane casually replies to fight "Anyone not wearing a primary color."
Lothor: How long have you been working here? You make him big, okay? They blow them up and we make them big, it happens everytime. How could you not get that part?
Another time, he tried to supersize six giant monsters at once against the Rangers, only for the PAM (Personal Alien Manager) to fail citing a "memory error". Zurgane tells him that they didn't pay for the memory upgrade, so they can only enlarge one monster at a time. Lothor curses at this, complaining that as future ruler of the world "I need big monsters!" and settles for enlarging one and making the rest fight while small. (This was also a bit of an Inside Joke- Disney wouldn't let the crew have more than one big monster per episode due to having a smaller budget than before.)
Tori's just been deposited back on a crowded beach from an alternate universe.
Tori: What's going on here? Dustin: Giant butterfly attacking the city, you know, the usual." Tori: It's really good to be back. Ready? Ni-...we're, uh... Hunter: Uh, what about the people? Blake: Yeah, not here. Dustin and Shane walk off to left of screen, Tori heads right, Hunter follows Tori Tori: Guys, this way! Hunter makes beckoning motions
Lampshading why people still live in Blue Bay Harbor, despite monster attacks. "Why do you think housing prices are so low?"
Lothor on the Green Ranger: "When are they going to run out of colors?!"
"The next person to use a made-up word has to put a dollar in the made-up-word-jar!"
"You know what the worst part is? It's not even butter. We're gonna be destroyed by ARTIFICIAL FLAVORING!"
Cam walks in the others practicing for a talent show at Ninja Ops. "Hey, it's the kids from Fame!"
