Percy has so much trouble deciding whether to stay year round or go to seventh grade. If he went to 7th grade he would be able to see his mom more often but if he decided to stay year round he would be able to interact with people just like him.
"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(:
