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!"
