Little Jonny

It was the first day at primary school for a new teacher and she was rather nervous. The classroom assistant told her to relax, as they were a pretty good bunch of kids except for one who was prone to swearing. So the day was going pretty well when the teacher decided to have a word game. She rounded the kids up and asked them if they new a word beginning with A
" Arsehole " shouted a little lad from the back." now Johnny that's very rude - I wont have language like that in my class " said the teacher." ok then can any one give me a word beginning with b " she asked, and straight away Johnny shouted out " bollocks ". " now I'm not going to put up with this fowl language Johnny " said the teacher. She was about to ask the class for a word beginning with the letter c till she saw a smile coming across little Johnny's face, so she decided to give c a miss.
" Ok class does anyone know a word beginning with d? "- "Dwarf " shouts Johnny," very good "said the teacher," tell me Johnny - do you know what a dwarf is?"
" Yes miss - its a little c*nt that's about 3 foot tall".............
