On my recent trip I chose to do a night dive. Since neither my lovely
wife nor any of the McDuffee clan made similar choices, I recruited
one of the boat's divemasters to be my buddy.

During the dive, I spotted a pufferfish.  I signalled to my buddy, who
then swam up to it and scratched the hair of it's chinny chin chin.

When we were back on the boat I told him about the recent, (as
reported on rec.scuba, probably by cdnn) incident of a divemaster
getting bit by a pufferfish.  He was surprised that it happened, but
agreed that if it happened to him, it would have been his own fault.

If at first you don't succeed, you run the risk of failure.
