Humorous jokes about kindness

A private school teacher found a flea on her body and threw it on the ground. The student said, "This flea seems to be the same as my mother's." Mr. Wang was overjoyed and thought he could take advantage, so he asked, "Where did the fleas on your mother come from?" The student said, "The fleas on my mother belong to my father." The gentleman asked, "Where did the fleas on your father come from?" The student said, "The fleas on my father belong to my teacher and mother."
