40 Best Family Guy Episodes Ranked, According To IMDb

In "Switch the Flip," Brian Griffin, ever the desperately lonely and deluded ladies man, falls in love with Brandee, the voice of an Alexa-esque smart speaker. To impress the A.I., Brian buys a ton of expensive stuff, only to have it repossessed, prompting a concerned Stewie to build a body-swapping device — he'll place his personality into Brian's body and get his life under control. While they're switching back, however, Peter and Chris barge in and get in the way, leading to a four-way swap: Stewie and Peter switch, as do Brian and Chris. And there's a ticking clock to get everybody back where they belong, because an extra-randy Lois is about to go away for a romantic weekend with Peter — or whoever happens to be in Peter's body, and nobody wants that to be Stewie. A high-speed car chase ends with the family crashing into a power pole which makes a transformer malfunction and send the body-switching rays out into all of Quahog, requiring Stewie leading Brian (through others' bodies) to fix the machine and return everyone to their biological home. It works, although not before Brian's greatest fantasy comes true — while stuck in Peter's body, he gets to enjoy the sexy weekend with Lois.
