Parent jokes

Teddy came thundering down the stairs, much to his father's annoyance.
'Teddy,' he called, '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 civilised human being.'
There was a silence, and Teddy reappeared in the front room.
'That's better,' said his father. 'Now will you always come down stairs like that?'
'Suits me,' said Teddy. 'I slid down the bannister.'
