A boy was teaching a girl arithmetic,joke

he said, it was his mission.
He kissed her once; 
he kissed her twice and said, “Now that’s addition.”

In silent satisfaction, 
she sweetly gave the kisses back and said,
“Now that’s subtraction.”

Then he kissed her, she kissed him,
without an explanation.
And both together smiled and said,
“That’s multiplication.”

Then her Dad appeared upon the scene 
and made a quick decision.
He kicked that boy three blocks away and said,
“That’s long division!”
hmm.haha
