Little Johnny was practising the violin in the living
room, while his father was trying to read. The family dog was at there too,
and, on hearing the screeching sounds, began to howl. Johnnys father listened
to the dog and the violin for as long as he could. Then he jumped up, slammed
his newspaper on the floor and yelled, For God’s sake, can’t you play something
the dog doesn’t know?
