Jerry's roof is steep, so he decides to use a safety line.  He tosses ski-tow rope over the rooftop-one end around his waist and the other end securely tied to a stationary object on the ground.  Jerry knows lots of people are injured in at-home accidents.  He's very safety conscious.

Precautions in place, Jerry begins to caulk the vent pipe collars on his roof.  Oh, did I mention that the stationary object he ties the other end of the rope to is the tow-ball on his four-wheel? Not a good decision!

Jerry is busy caulking on the front side of the roof when his wife decides to go to the mall.  She jumps into Jerry's four-wheel, checks the mirrors, looks both ways, and eases out into traffic.

It must be providence that makes Jerry's wife glance once more into the rear view mirror.  At first she doesn't recognize the flying object as her husband.  It's the bright red jump suit vaulting over the rooftop that cinches it.  "Jerry?!" she thinks in a silent scream.

Next, Jerry careens down the rear side of the roof, and plunges back-first into a cluster of holly bushes.

Paramedics lift Jerry gently out of the prickly holly, pluck a dozen thorns from his rear-end, ease him onto a backboard, then carry him aboard a high-rise ambulance.  Jerry is incoherent.  His hysterical wife screams repeatedly at the departing EMT unit, "Oh God, Jerry, I'm so sorry-I didn't know..."

A responding deputy sheriff is told by a neighbor that Jerry crested the roof looking all the world like Santa Claus, but without the eight tiny reindeer.

Jerry's flying episode is bizarre, and not the least bit funny.  But the reporting deputy sheriff says there is not one-not one-neighbor who can describe the incident without fighting back at least a tiny bit of laughter.
