Impudent child,

It is a shame you did not discuss these "free tours" with me in advance,
else you may have found that I am not particularly inclined to receive
unwelcome visitors. It is also a shame that you shall not be giving
those tours you so foolishly offered, as the Chaos Lords deign to
associate with you no longer. Free tours of your internal organs,
however, may be arranged.

There is a valuable lesson to be learned here. Let us see if you can
gather what it is.
