Undertakers

        A  guy went for a job at a local undertakers.
On his first day they had a call from some guy's wife saying that her
husband was dead and he wanted to be buried at sea. Never having done a sea
burial before they decided to read up on it. Apparently the body needed to
be buried in at least 30 feet of water.

        The next day they hired a small boat and went out into the bay.
After about ten minutes they picked a spot. The new guy said that he was a
good diver and would swim down to see how deep the water was.

        He dived in, and a minute later surfaced saying "It's no good, it's
only 10 feet deep here."

        They sailed further out, he dove in again... "It's still no good,
it's only about 25 feet deep."

        They sailed on for a further ten minutes, he dived in again. After
a few minutes he surfaced...

        "It should be fine here, it's at least 40 feet deep.. Pass me the
fucking shovel then...."
