Charmed/Funny

Piper's line "Don't treat me like a baby factory. I can sit myself down" due to Holly Marie Combs' delivery.
- In general, Piper is a gold mine for these. Holly Marie Combs might have some of the best snarky deadpan delivery this side of Bea Arthur, and she put it to good use.
In the Season 6 episode It's a Bad, Bad, Bad, Bad World, the Mirror Universe version of Barbas. Seeing the Demon of Fear become the hippy-like Demon of Hope is hilarious!
- Warhammer 40,000 taught us being a demon of hope isn't always a good thing.
Any appearance by Danny Woodburn as the leader of the Seven Dwarves.

Head Dwarf: Somebody here eat a poison apple?

"Dreams are just harmless, erotic fun".
Phoebe freaks out about when she finds out her date is a demon via Premonition at P3. Her solution? Run and tell Piper, who promptly rolls her eyes, freezes the jam packed club, wastes the demon, then unfreezes the room. And no one noticed. Probably a Crowning Moment of Awesome, made funny by Piper's next line:

Piper: My sister the demon magnet.

- It's just so true.
The Day the Magic Died when the Villain of the Week had to go to the manor on foot, and leave by cab.
"I'm being stalked by psycho killers and I hide in the shower!?"

Cronus: "We really should do something nice for the leprechaun community."

Chris pouting about how Wyatt had super powers while still in the womb.
Billy Zane as a delusional demon who thinks he's Robin Hood in Carpe Demon.
In "12 Angry Zen," Paige's nonchalant line at the top of the Golden Gate Bridge, "Oh my goodness, Henry just fell off the bridge. I'll have to call you right back."
In the Season 6 Episode "I Dream Of Phoebe", Chris, the son from the future, has to hurry to get his parents back together or else he won't be born. However, his wish that Leo and Piper should sleep together naturally freaks Paige out a little:

Paige: Oh my god, you are sick! What is wrong with you? You're disgusting!
Chris: No...
Paige: You are some creepy registered sex offender from the future.
Chris: No, no, no...
Paige: Oh my god, you are so gross.
Chris: I'm Piper and Leo's son.
Paige: What?

- Also:

Chris: If they don't screw, I'm screwed!

In "Charmed Noir," Paige and Brody are trying to solve the mystery, while Piper, Phoebe and Leo are reading it in the real-world. Paige and Brody disagree about what they should do next, but Paige's idea would ultimately lead them into a trap. To warn them, Phoebe writes in a plot twist: a piano dropping beside them.

Brody: Guess your sisters agree with me.

Phoebe turning into a mermaid.

"I wanna play with my under sea friends and I wanna lay out on a rock and comb my hair.

- Phoebe is set to have an interview with Nancy O'Dell so what does Piper do? Cover Phoebe's mermaid parts with bubbles and have the interview done while she's in the bathtub.
The entire episode "Sense And Sense Ability" where Phoebe loses her hearing, Piper her sight and Paige her voice. Paige tries to mime that the monkey stole her voice and the best Phoebe can come up with is:

Phoebe: "Ooh, you're angry, you're pissed, you're....PMS monkey?"

From "Love's A Witch" where Paige orbs an apple into Phoebe's mouth to shut her up.
The scene in "From Fear to Eternity" where Andy confronts Prue over her seeming connection to a string of murders.

Prue: What exactly are you implying?
Andy: Prue, if you were in my shoes, what would you think?
(Prue glances at his somewhat tacky sneakers, which Darryl had made fun of earlier).
Prue: First of all, nobody should be in those shoes.
Darryl: Told you.

In season 3 episode "All Halliwell's Eve" during a Halloween party at the end, Cole comes dressed as an angel with the full wings and halo.
