PRESENTATION OUTLINE
The Rainbow Cows are just usual cows but their owner is very inconsiderate and strange.
Their owner, who is a farmer, always splashes paint outside of his house, particularly where the cows are.
One day, the farmer splashed red paint on a cow and blue paint on another cow. When they mated, their calves were purple.
The same thing happened to other cows, except that they were different colours.
One day, the farmer splashed many colours on two cows. When they mated, their colours of their calves were a weird colour.
This kept happening until the calves were all weird, strange colours so they had to be painted white and black again.
