The salesman and the system analyst took off to spend a weekend in the
forest, hunting bear.  They'd rented a cabin, and, when they got there, took
their backpacks off and put them inside.  At which point the salesman turned
to his friend, and said, "You unpack while I go and find us a bear."
Puzzled, the analyst finished unpacking and then went and sat down
on the porch.  Soon he could hear rustling noises in the forest.  The noises
got nearer -- and louder -- and suddenly there was the salesman, running like
hell across the clearing toward the cabin, pursued by one of the largest and
most ferocious grizzly bears the analyst had ever seen.
"Open the door!", screamed the salesman.
The analyst whipped open the door, and the salesman ran to the door,
suddenly stopped, and stepped aside.  The bear, unable to stop, continued
through the door and into the cabin.  The salesman slammed the door closed
and grinned at his friend.  "Got him!", he exclaimed, "now, you skin this
one and I'll go rustle us up another!"
