Meowth said a similar line in "Double-Time Battle Training"
As for funny lines, here are one (search for "Pokemon") or two pages which have some gems like:
* Brock: "If they built a temple to honor Psyduck, they weren't hidden, they were lost."
* Misty: "You can stuff your greedy little face after we find a Pokemon Center!"
* Ash: "My face is little?"
But Team Rocket wins this with:
James: I AM A FLAMING MOLTRES!
Meowth: That outfit... where'd he get it?
Jessie: I think that costume came right out of his closet.
