Time Out for Trouble ★★★★

A homicidal clock hates the dim-witted housewife who insulted her and so contrives a series of household objects to injure the lady, while explaining the best methods to avoid accidents, which are: Feel Your Feelings, Beware of Boredom, Watch for Danger. Also there's a digression about how a drunk gets hit by a car because his wife is boring, which he didn't realize until after they were married because parts of her were so hot (we see said parts in montage). 

Basically the best movie ever.
