It would appear that this problem has been known since the days of William Shakespeare? :lildevil:
POLONIUS [behind the arras]. What, ho! help, help, help!
HAMLET [draws]. How now, a rat? dead, for a ducat, dead.
He makes a pass through the arras
POLONIUS [falls]. O, I am slain!
QUEEN. Oh me,what hast thou done?
HAMLET. Nay, I know not,
Is it the king?
He lifts up the arras and discovers Polonius, dead
QUEEN. O what a rash and bloody deed is this!
HAMLET. A bloody deed - almost as bad, good mother,
As kill a king, and marry with his brother.
QUEEN. As kill a king!
HAMLET. Ay, lady, it was my word....
[to Polonius] Thou wretched, rash, intruding fool, farewell!
