(Irish joke, sorry guys). A teacher is giving an English lesson on the word ""Contagious""... ...She asks the class for examples of when they have heard the word 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?"" (apologies for the token Irish name). ""Well, our neighbour is painting his fence with a toothbrush"", said Paddy, ""Dad says it's going to take the contagious!""
