"A Landslide Brought Me Down...."

 Never trust a little brother to do a big brother's job....look at this control tower JD built.  Just look at it! First of all, he built it on an inclined plane of books.  Bad idea.  Secondly, he completely forgot to bolster it from the inside.  A little lateral shaking cause by a Daisy-quake and bam!  Down it slides onto the helpless innocent train, poor conductor trapped inside.
  Ok, so there's small possibility that it twas I that built the train control tower...and I may have been chasing Daisy at the time said tower fell.  But let's not waste time arguing semantics here....the important thing is we've all learned a valuable lesson.  Never let your trains wander off their tracks...it's a jungle out there.
