Some simple puzzles

Here are some simple puzzles and jokes which I like!

First, a joke: A foreman was in charge of a building site, and he was convinced that one of the workman was stealing material from the site. Every day, the workman wheeled a wheelbarrow out of the site with some sacking in it. Every day, the foreman carefully searched the barrow, and the man, but could find nothing. Finally, the building work was over, and they left the site. Later on, the foreman met the workman, and they chatted about old times. The foreman ended up by saying, "Look, I know you were stealing something! It's sending me mad. I won't do anything about it, but please tell me what it was!"

As a further comment on the last problem, sometimes at work managers put more people on a project to get it finished quicker. We used to say (under our breath) "Make a baby in one month. Use nine women if necessary."
