Brother goes and hits his sister in the back of the head.
She screams, "OW!" Then chases after him as he runs away.
He slips on a bannana peel as he tries to make a get away and falls flat on his
butt getting the breath knocked out of him.
Then his sister comes up and smirks saying, "
Karma."
Brother replies sarcastically, "What are you, the
karma duke?"
