Johnny the pottymouth

Johnny was in kindergarten and he just loved swearing, and all of the teachers hated him because of it. One day in class they are learning about the alphabet. The teacher starts with A and asked the class if they know any words that start with the letter A, Johnny raises his hand and the teacher thinks to herself, "I can't call on Johnny he's just gonna say ass or asshole" so the teacher calls on Lisa, and Lisa says Apple. They move on to B and the teacher asks the class is they know any words that start with the letter B, Johnny raises his hand again and the teacher thinks to herself "I can't call on Johnny he's just gonna say bitch" so the teacher calls on David, David says Banana. They move onto the letter C and Johnny raises his hand again and the teacher knows she can't call on him because he's just gonna say cunt. So the class goes through all of the letters until they get R, and like always, Johnny raises his hand, well this time the teacher thinks to herself "what bad word is there for R?" So she calls on Johnny and Johnny says impatiently "Rats, FUCKING RATS"
