According to this site, this is the real footage of this particular clip:
The scene where Lois and Peter are naked and high while on the couch was shown differently on the FOX version. The FOX version showed Lois and Peter wearing underwear while on the couch (instead of being completely naked, despite Stewie’s line near the end of the scene where he states that Peter and Lois are nude) and the entire part where Lois whispers to Brian, “Hey, he’s knocking on the back door. Should I let him in? I’m a-scared!”, with Brian totally bewildered about her statement was cut. This is the full DVD version of the clip.
