A teacher asks if anyone in the class can use the word "contagious" in a sentence. Jenny puts her hand up and says "My mum says we should stay home when we're sick incase we're contagious." "That's right" the teacher says, "Anyone else?" Susie says "My grandma says a smile can be contagious." "Very good" says the teacher, "Anyone else?" Little Johnny puts his hand up and says "My dad says our neighbour is painting his house with a two inch brush and it'll take the cunt ages."
