Coyote Piper - S3-E9
Trivia: The title for this episode is a reference to the film Coyote Ugly. The film is set primarily in a bar named Coyote Ugly where the 'coyotes' dance seductively on the bar. In this episode of Charmed, Piper dances on the bar at P3. Additionally, the actress who plays the main character in Coyote Ugly is named Piper.
Plot hole: When Gith takes the potion from Chris, he ends up stomping on it and shattering the potion bottle - making contact with the potion. We've seen that potions don't have to be thrown by someone who's even a witch for them to work (like when Cole's powers were stripped etc) so why on earth would he do this? And how did it not vanquish him? There are other ways he could have gotten rid of the potion that didn't involve a way that really should have vanquished him.
Cole: Phoebe, I love you. I don't know what's going on but maybe I can help. Would you like me to kill someone for you?
Answer: "Hush, Hush, Hush" Paula Cole.
