Three men walked onto an airplane, each carrying a small paper bag. They found that they had seats beside each other, and of course, talked.
They found that they all happened to hate, absolutely hate, traditional pb&j sandwiches. Well, the first man opens up his lunch sack and finds a pb&j sandwich. Since he doesn't have anything else to eat and food wasn't offered on their flight, he ate it. The others opened up their bags and found exactly the same thing.
Next week, they happened to find themselves in the same seat on the same plane. They opened up their lunchbags, with they same end as the previous week. They made a promise with each other: Next week, if they got pb&j sandwiches, they would jump out of the plane.
That Saturday, they found themselves together again. Well, the first opened his bag, found a pb&j sandwich and jumped out the plane.
The other two did the same.
The news the next day showed three older women. The first cried and said, "Oh, my baby! I killed my baby!" The second cried, "Oh, my baby! I killed my little boy!"
The last rolled her eyes and said, "Don't blame me, he packed his own lunch."
