Sam Spade gives credit to the wrong source

In the episode entitled "The Queen Bee Caper," Sam discovers the dead body of Ursula Cavanaugh, who has been stung to death by bees. He quote the verse, "O death, where is thy sting?" but mistakenly gives credit to Shakespeare. Shakespeare may have used that expression somewhere in his writings, but the apostle Paul wrote it under divine inspiration long before the playwright came along.
