Teacher told the children to draw a picture of the flight into Egypt. She looked at Johnny's sketch and said "that's very good. Johnny, but what's that black mark on your picture?"
Oh that, answered Johnny. You said that Joseph was to take Mary and baby Jesus and flee into Egypt. Well, that's the flea!
Amusing IRL. We read the same story in first grade religion class. In order to improve their phonics and comprehension skills, I presented a simple version of the story, words only, on a smartboard. The children’s assignment was to write an original sentence using the words on the board and draw a picture to go with it.
After a time the children took turns sharing their work. One boy stood up and read his sentence, “Mary and Joseph and Jesus take a flight to Egypt.” His picture showed an EgyptAir 787 jet with three windows and an arrow pointing to the bottom of the plane. In the back window was St. Joseph, in front of him, Mary holding up baby Jesus, in the very front, the pilot. Beneath the arrow was written, “donkey!”
