One of my most frequent citations is from MAD's take off on Chuck Connors' "The Rifle, man."

As they are wandering through the West, with Chuck blowing people away on sight, his son asks: "Daddy, you say you're a peace loving man; so how come you keep killing them?" The reply: "There ain't nothin' so peaceful as a dead man, son."

Sadly, it is still relevant today.
