WHAT?
In the closing shot, the children playing in the street are chanting "The Farmer In The Dell."
But with with one exception: instead of the verb "takes" (as in "the Farmer takes the wife," "the wife takes the child," etc), the children say "KILLS" (as in "the Farmer KILLS the wife," "the wife KILLS the child," etc)).
Now - I've heard of poetic license before, but changing the line of a classic children's song for dramatic ironic effect???
"Don't call me 'honey', mac."
"Don't call me 'mac'... HONEY!"
