Plumber


A doctor stayed home from work one day because his toilet was
clogged, and he couldn't get a plumber to make a housecall at
any other time.

The plumber finally arrived several hours late.  He spent about
15 minutes clearing the blockage in the toilet, and then he told
the doctor, "That'll be $150, please."

Almost instantly, the doctor began to shout, "Are you out of 
your fucking mind???  *I* am a doctor, and even *I* don't make
$150 in 15 minutes!"

But the plumber explained, "I know how it is, doc.  *I* used to
be a doctor too, but I had to switch professions so I could
start making some decent money!"
