"Sentences" is the punning word in #1, for judges give out sentences. And teachers, as well. Get it? Sentences?
"Manor" is the punning word in #2. Get that? Castle? Home? Manor instead of manner? A pun is a joke exploiting the different possible meanings of a word or fact that there are words that sound alike but have different meanings.
Another example of a pun is:
The pigs were a squeal.
I wondered why the baseball was getting bigger. And then it hit me.
Do you understand now? LOL. (: Hope this helps(:
