The New Archie and Sabrina Hour

Weatherbee-Fuddled (1x15)

:

The witches don’t like what they hear when Mr. Weatherbee gives a lecture on "Superstitions and Other Nonsense," so they cast a spell on him to make everything he says come true. It starts out fairly harmlessly, but eventually, the witches lose their powers and everyone on earth is transformed into a bird.
