Here's a couple of quotes from the Pokemon series that are worth a chuckle. Though I've tried to limit this to mainly Team Rocket quotes (since we know they are the PUN MASTERS), you'll find that occasionally, the twerps have a gem or two, as well. Obviously, the episodes without quotes, just don't have any quotes listed. Probably because I (a) never saw the episode; (b) was too lazy to find any; or (c) was just flat out too lazy. I tried to only list the best quotes. If there was an episode with nothing noteworthy, it's not listed either.

POKEMON, I CHOOSE YOU! (episode 1)
POKEMON EMERGENCY! (episode 2)
ASH CATCHES A POKEMON (episode 3)
CHALLENGE OF THE SAMURAI (episode 4)
SHOWDOWN IN PEWTER CITY (episode 5)

CLEFAIRY AND THE MOONSTONE (episode 6)

"Nice guys finish last!"
-Jessie

"We just went from worst...to first!"
-Meowth

WATERFLOWERS OF CERULEAN CITY (episode 7)

"It’s time like these that make me want to go straight."
-James (The Single Most-Referenced James quote--ever!)

"Now I know what it feels like to be all washed up--"
"--but we’ll NEVER come clean!!"
-James and Jessie, respectively

"Thanks...but I'd rather earn my badges."
-Ash (because I found this quote terribly ironic.)

THE PATH TO THE POKEMON LEAGUE (episode 8)

“He’s getting a big head.”
“Yeah, but his brain is still the same size.”
– Misty and Brock, respectively, (concerning Ash)

 “Choreography killed the cat!”
-Jessie, referring to Meowth's dancing skills

 “My leg fell asleep!”
“I wish your mouth would!”
–James and Meowth, respectively

"Stop pussy-footing around!”
“Just biting my time…”
“AHH! THE MOMENT OF TOOTH!”
 –Jessie and Meowth, respectively (referring to Meowth's playing around with Sandshrew, then Meowth biting Sandshrew, then Meowth's teeth falling out due to Sandshrew's tough exterior)

THE SCHOOL OF HARD-KNOCKS (episode 9)

"She can violate MY rights!"
-Brock, referring to Gisele

 “A wise Pokemon trainer should never get involved in a cat fight."
–Brock (to Ash, concerning Misty and Gisele's rivalry)

"We frolicked that night...”
“For our futures seemed bright...”
 –James and Jessie, respectively (concerning the night prior to the Pokemon Tech entrance exam. Mild sexual undertones, anyone?)

"At least you're the top of the bottom!"
-Meowth, in a sardonic effort to console Jessie and James

"I liked them better when they were evil!"
-Meowth, after Jessie and James violate his personal space with affections for "always saying the right thing" see above quote

"She's even more conceited than we are! (shocked tone)"
"Yeah, but she's really cute (googly eyes)!"
-Jessie and James, respectively (commenting on Gisele. Perhaps proof James isn't gay? Or is it proof that James is attracted to Gisele and not Jessie? Pick your battles, Rocketshippers. Personally I think Gisele is just a little kid and James sees her as such. Hence the wording "cute" and not "pretty," "gorgeous (as Jessie and James describe themselves)," "beautiful" or "flat-out  sexy erotic momma!")

BULBASAUR AND THE HIDDEN VILLAGE (episode 10)

CHARMANDER, THE STRAY POKEMON (episode 11)

"She's really pretty. I don't think I've seen any one as pretty as her..."
"--What are you talking about? She looks like all the other Joys!"
"Yeah...it's a...joyful...world."
-Brock, Misty and Ash, respectively. (Ash tries to make a pun, Team Rocket-style...well, good for a first timer...)

"You have to be a rocket scientist to outsmart us...the Team Rocket scientists!"
-James

HERE COMES THE SQUIRTLE SQUAD (episode 12)

"I want a donut!"
-James (perhaps one of the most over-used James quotes on the net; refers to the Squirtle Squad stealing Team Rocket's lunch)

"I'm really hungry, let's get lunch--!"
"--But no pizza!"
(Jessie beats them both with a paper fan)
-Meowth and James, respectively

"You're threatening US? We're Team Rocket--we do the threatening!"
-Jessie

"Don't you ever raise your voice to me again, you bad, bad human!"
-Meowth, to James

"We'd like some flash powder...and dental floss!"
-Jessie, demonstrating how important oral hygiene is.

MYSTERY OF THE LIGHTHOUSE (episode 13)

ELECTRIC SHOCK SHOWDOWN (episode 14)

"It's going to fight in the name of all Pikachus!"
"That's soooo beautiful!"
-Meowth and James respectively, tears streaming down their respective faces

"That was very disturbing."
"Thanks for your support! Bye, Team Rocket!"
"How did they know it was us?!"
"Lucky guess!"
-Brock, Misty, Meowth and Jessie, respectively, concerning Team Rocket's exploits as the "competitor's cheerleaders."

POKEMON SHIPWRECK (episode 16)

(James and Jessie fall into the ocean)
"Team Rocket is really slipping."
-Meowth

"A young and beautiful woman will cause you a terrible misfortune."
"I don't need a fortune teller to tell me that. Some woman is always causing me misfortune."
"...who do you mean?"
-Creepy Old Lady, James, and Jessie, respectively

"I'm Brock. Hm."
"Brock's back!"
"I'm James. From Team Rocket. Eeeeee!"
"*groans* He's back."
-Brock, Ash, James, and Jessie, respectively.

"Staying up late is bad for your skin, it makes you irritable and ruins your appetite!"
-sage advice from Nurse Joy

"...you don't want to go?"
"Of course I don't want to go! I don't want to go! I don't want to go!"
-Jessie and James, respectively

(Jessie blows a hole through the maiden's ghost with a rocket launcher)
"Hey girl! You can't take him! You don't stand a ghost of a chance!"
-Jessie

"You really DO care!"
"...it's not you. Girls like her disgust me, always waiting around for her man, like his faithful little pet. She cries, but I'd say, 'see ya later!'"
-James and Jessie, respectively (one of my personal favorite quotes)

BYE BYE BUTTERFREE (episode 21)

"Let's do something networking!"
"Nothing but net!"
 – unrelated net puns by Meowth and James, referring to the giant net they're using to ensnare Butterfrees

"We're at our best when we're at our worst!"

"We're catching all the Butterfree!"
"There's never been a happier...me!"

"Sometimes being evil doesn't pay--"
"--especially when the payment is in electric volts!"
-Jessie and James, respectively.

CAN'T BEAT THE HEAT (episode 272 )

"I'll design the cutest outfits! We can advertise and write a jingle!"
-Jessie (who is obviously very business-minded)

"It's out of the poor house and into the horn of plenty!"
-Meowth

GOTTA CATCH YA LATER (episode 273 )

"Imagine that, a team of three losers."
-Jessie (obviously the irony is lost on her.)

"Do you believe in love at first sight, or should I walk by you again?"
-Brock, not realizing that his pick up line is the oldest in the book

"There's more important things in this world than money--which means even if we had any we wouldn't give it!"
