There once was a race of smurf-like creatures called "Trids".
The Trids were happy, peaceful, folks, who lived in a village at the
base of a mountain. Part of their culture was an annual ceremony, in
which the whole population would go up to the top of the mountain for
a grand celebration. On the way to the mountaintop there was a river
that they had to cross, and a single bridge was the only way across.
One year, as the annual trek was underway, the Trids came to
the bridge only to discover a huge troll sitting in the middle of the
bridge, blocking the path. One of the Trids was brave enough to step
onto the bridge and walk up to the troll, attempting to pass by. But
as he got near, the troll picked up the Trid, and drop-kicked him,
sending him rolling down the mountainside back toward the Trid
village. Another Trid attempted to cross the bridge, but was met
with the same reaction from the Troll, and went rolling down the hill
after the Troll kicked him.
As a third Trid walked onto the bridge, a Rabbi happened to be
walking along the riverside, just in time to see the Trid get kicked
into the air and roll down the mountain. Outraged, the Rabbi stomped
up onto the bridge and began walking toward the troll. As he got
near, the troll stood to one side, allowing the Rabbi room to pass.
The Rabbi was very surprised at this, and asked the Troll, "Why are

let me pass?". And the troll replied:
