A biologist phones his wife from his office and says,
"Honey, something has just come up, I realize its not my
field season, but I have to visit my field site for a week.
So, would you pack my clothes, my field equipment and my
blue silk pajamas? I'll be home in 1 hour to pick them up."
A week later he returned. "Did you have a good trip, dear?"
his wife asked.
"Oh, it was just a typical field trip, you know, work work
work," he exclaimed, and added "But you forgot to pack my
blue silk pajamas." "No I didn't," she replied. "I put them
in the box of field equipment!"
