OK here we go, all you Team Rocket fans...rack your brains, check the Internet, whatever...let's try to assemble all of Team Rocket's best quotes! Please include the episode the quote came from if you can. (Yes, this includes funny versions or partial versions of their motto.) I'll be adding more later as I find them. The quotes below are in no particular order.

Who Gets to Keep Togepi?
James: We have a proud tradition of failure to uphold!

Pokemon The Movie 3
Jessie: Who cares if we failed this time!

Octillery the Outcast!
Jessie: Aaaahh! It's my wretched recurring Remoraid nightmare come true!
James: I see no resemblance to that first grade teacher of yours.
Jessie: Well that's a relief, but you can't blame me, Ms. Crabtree was really scary.

The Mystery is History
TR grunt: "What are your orders sir?"
Namba: "The same thing I always order! Fish sticks!"

Jessie: "Wasn't that Cassidy and what's-his-name?"
James: "It's Butch, he's a little sensitive about that."

A Promise is a Promise
Jessie: "We'll coerce those creeps into creating chaos, causing a calamity, and in the uncontrolled commotion we'll capture those condors!"

Dues and Don'ts

Meowth: Touchdown, that's right!

James: "How do you know it's a Blizzard attack?"
Jessie: "Maybe because we're in a blizzard?"
James: "Oh...that makes sense."

Talkin' 'Bout an Evolution!
Meowth: "What's more ridiculous, gettin' lost or us followin' dem gettin' lost?"

James: "That's just not right! Zero is a gross exaggeration, we are at least 2 to 3 percent worthwhile!"

Meowth: "I'm gonna take a little nappy-poo." (puts its face down in the water)

Pokemon the Movie 2000
Jessie: Well if things are gonna get ugly, we may as well try Weezing!

Jessie: If that kid thinks we're here for trouble...
James: ...we're certainly going to burst his bubble!

James: ...we've undergone a transformation!
Jessie: Though it's way outside our usual range...
James: ...we're going to do something nice for a change!
Jessie: Jessie!
James: James!
Jessie: Up till now Team Rocket's been quite unscrupulous!
James: Being good guys for once would be super-dupulous!

Jessie: So then we're not bad!
James: That's good!
Meowth: What if da boss finds out?
James: That's bad!
Jessie: So we'll start our own team!

Hassle in the Castle
Jessie: To protect the world from scratching and itching!
James: To finally stop all of Jessie's...complaining!
