You have to stop this

WARNING!
YOU must not go any further.
HAVE you any idea of what lies between these perilous pages?
(How could you? Except perhaps if you were to catch a whiff of musty mummies or dusty tombs...)

TO keep reading would be foolish.
STOP immediately.
(Please,I beg you.)

THIS has really gone too far...
(You have to stop this.)
