Paige: Power. Power's good. I like power. Why do I like power?
Siren Song - S5-E4
Phoebe: Woman to woman, okay. Cole was the love of my life, and I'm finally learning to live without him. Calling him for a favor would open a can of worms that I've been trying to close.
Elise: Woman to woman. If you're still describing this guy as the love of your life, then the can is open, the worms are out, and you may as well use them to go fishing.
Piper: Darryl, I'm sorry, but what do you want me to say? My sister was just possessed with a supernaturally born killer and my husband is in 1994, and I do not mean in the fashion sense. He time traveled back with my other sister so the only one left to help me is you.
Piper: Don't act blonde.
Darryl: Oh, no creepy talk in the precinct. Will you just keep down the creepy talk.

I've Got You Under My Skin - S1-E2
Piper: Don't put me in the middle.
Prue: I'm not. You were born in the middle.
Answer: That was a mistake in the series.
Also, the episode is called 'Babies First Demon' and this alone tells us that it's Wyatt's first time in the field (so to speak) and as the sisters say, they've done a good job of clearing up their own magical messes so far. Nobody really knows how advanced Wyatt's powers are, or will become. That's why the cleaners appear, to nip things in the bud. The Cleaners didn't want to chance that the sisters could clean Wyatt's magic up, just incase they couldn't. Therefore intervening themselves, just in case.
