After noticing the resemblance between one thug in China O Brien and Ash Ketchum she yells "Gotta catch 'em all, motherfucker!"
She did a tribute to Rachelle Lefevre and makes several references to Big Wolf on Campus, her favorite show growing up. She admits the only reason she reviewed Teen Sorcery was because Aimée Castle was in it.
She made a quick nod to Pierre Kirby while riffing Howling IV. "What a useless guy!"
While watching Gooby, Lupa and Liz get so freaked out that Liz jokes, "This is the last known footage of this kid, isn't it?" This prompts Lupa to respond, "Aw, snap, this is going into Slender Man territory!"
During one of her "fashion police" segments on Phoebe's dress sense, we hear "Bad Boys" playing throughout.
The Imperial March starts playing as the Charmed Ones get out of an elevator and into the FBI's headquarters at the beginning of the final ME about Charmed, which covered season 8, in which the sisters had finally and fully transitioned into EVIL.
The Charmed Ones immediately growing suspicious (read: jealous) of a new, younger witch on the scene who's making them look lazy. We get a truly hilarious dub of James Doakes' "Surprise motherfucker" as Phoebe glares at Billie from behind closed doors.
