Practice Makes...
Little Johnny was practicing the violin in the living room while his father
was trying to read in the den. The family dog was lying in the den, and as
the screeching sounds of little Harold's violin reached his ears, he began
to howl loudly.
The father listened to the dog and the violin as long as he could. Then he
jumped up, slammed his paper to the floor and yelled above the noise, "For
Pete's sake, can't you play something the dog doesn't know?!"
