Synopsis for
"Family Guy"
Stewie Kills Lois (2007)

In what could be described as a "DOUBLE DOG DARE" sort of episode Brian's Birthday Present to Lois places her and Peter on a cruise-ship. Stewie's talk of "Torture/Death" of Lois for when she returns, is belittled (disparaged) by Brian, which forces Stewie to act on his lifelong desire. A year after the visually detailed "Machine-Gun Execution" of his mother, Peter is incidentally framed for the murder, of his beloved, by Joe (and the guys) of which he is found guilty. The final scene of this two part episode, enters Lois through the Courthouse doors, accusing the actual guilty party (Stewie) of the malicious homicidal attempt.
