Shark bait..

[Josko]

Bryers and couple of his Australian staff are enjoying
a junket on a cabin cruiser, when Bryers falls
overboard. Before anything can be done, an
enormous shark approaches to within six feet of
the Bryers, but suddenly veers off in another
direction.

One staffer exclaims, "Did you see what just happened? That's an act of God!"

Another replies, "Nah, it was just professional courtesy."
