"You don't have to open the crates right in the middle of main street," Papa said.
"Rules and regulations say I've got to inspect the merchandise for damage," Mr. Larson said.
"You know very well, Nels," Papa said testily, "the only time you ever inspect anything is when the shipment is for me."
"Ain't nothing interesting in the others," Mr. Larson said. (1.76-79)
Mr. Larson uses the law, Tom-style, here, purporting to do good while satisfying his own interests. He wants to check out the new water closet, so he defends his nosiness by appealing to authority.

"T.D. will probably come out of this a hero to every kid in school," Papa said, and that is just how it turned out. (7.202)
Papa says this following Tom's confession of his role in framing Mr. Standish. While Tom may not get Mr. Standish fired, he gets what he and the rest of the students want: a return to Miss Thatcher's policies. Sweet victory.

"Ladies and gentlemen," Papa announced to the crowd. "I am pleased to report that Mr. Harvey and I have successfully installed the first water closet in Adenville. You will be admitted in small groups of not more than six at a time. Mr. Harvey will explain the mechanism of the water closet and how it works. He will also give each group a demonstration. As you leave please pass through the kitchen where Mrs. Fitzgerald will serve refreshments." (1.119)
Refreshments are obviously necessary, because if there's one thing that gives us an appetite, it's watching a toilet flush.
