Civil Suit Puns

The son came thundering down the stairs, much to his father's annoyance.
So he said, he said, "How many more times have I got to tell you to come down the stairs quietly? Now, go back up and come down like a civilized human being."
There was a silence, and the son reappeared in the front room. So his father said, he said, "That's better. Now will you always come down stairs like that."
So the son said, he said, "Suits me - I slid down the bannister."
