The proud father brought home a backyard swing set for his   
children and immediately started to assemble it with all the   
neighborhood children anxiously waiting to play on it.   

After several hours of reading the directions, attempting   
to fit bolt A into slot B, etc., he finally gave up and   
called upon an old handyman working in a neighboring yard.   

The old-timer came over, threw the directions away, and in   
a short while had the set completely assembled.   

"It's beyond me," said the father, "how you got it together   
without even reading instructions."   

"To tell the truth," replied the old-timer, "I can't read,   
and when you can't read, you've got to think."
