In October of 2006 Jacob and his father's business partner Mike Detjen
were injured in a horrific accident involving a trebuchet, a medieval
catapult, which was used to promote the Roloff's Farm. The trebutchet
misfired while Jacob and Mike were cocking back and reloading the
catapult sending the a 2000 pound counter weight crashing into them.
Mike received over 200 stitches while Jacob received a dent in his
skull which required surgery to relieve some of the pressure on his
brain. Both Jacob and Mike have made a full recovery.
