A teacher in Ireland is giving an English lesson and asks the class for examples of when they have heard the word "contagious" being used…

One eager child says, "Daddy says to cover my mouth when I cough because my cold is contagious!"

"Very good!" replied the teacher. "Has anybody else got an example?"

"My mummy says my laugh is contagious!" said another child.

"Great answer!" said the teacher, "How about you Paddy?"

"Well, our neighbour was painting his fence with a toothbrush." said Paddy. "Dad says it's going to take the contagious!"
