Johnny replied, "7 rabbits, Teacher."

The teacher asked again.

"Listen Johnny. If I gave you
 2 rabbits, plus 2 more rabbits,
 plus 2 more rabbits...
 How many rabbits would you
 have 'ALTOGETHER'?"

Johnny smiled, "that's easy,
Teacher, I would have 7."

"OK, Johnny," the teacher sighed,
"let's try it A DIFFERENT WAY."

"If I gave you 2 cans of pop,
 plus 2 more cans of pop,
 plus 2 more cans of pop.
 How many cans of pop
 would you have?"

"6 cans," said Johnny.

"OK," said the teacher.
"Now think of that with this question.
  If I gave you 2 rabbits,
  then 2 more rabbits,
  then 2 more rabbits,
  how many would you have?"

"7, Teacher," said Johnny.

"Why 7?!" the teacher asked
 exasperated.

Johnny replied, "because I
'ALREADY' HAVE
1 RABBIT at home!"
