which episode says "If you watch that video you die." in Family guy?

Mother Tucker

[MAIN PLOT]

Peter's Mom gets a divorce and dates Tom Tucker

Season: 5 Episode: 2

A cutaway shows a young girl giving the tape to Peter and warning him that if he watches it, he will die, similar to The Ring. Peter takes the tape anyway and plays it on the VCR. The tape in question turns out to be Mannequin and Peter dies, with his mouth wide open, just like Samara’s victims in The Ring.

Here's a clip of that scene:

It's the episode "Mother Tucker" and the video they were talking about is The Ring.
