“Doctors?" said Ron, looking startled. "Those Muggle nutters that cut people up?”
“Who's Kreacher?""The house-elf who lives here," said Ron. "Nutter. Never met one like him.""He is not a nutter," said Hermione."His life's ambition is to have his head cut off and stuck up on a plaque like his mother", said Ron. "Is that normal, Hermione?”
“Muggles have garden gnomes, too, you know," Harry told Ron as they crossed the lawn."Yeah, I've seen those things they think are gnomes," said Ron, bent double with his head in a peony bush, "like fat little Santa Clauses with fishing rods...”
“Ron, you know full well Harry and I were brought up by Muggles!” said Hermione. “We didn’t hear stories like that when we were little, we heard ‘Snow White and the Seven Dwarfs’ and ‘Cinderella’ —”“What’s that, an illness?” asked Ron.”
“I'll fix it up with Mum and Dad, then I'll call you. I know how to use a fellytone now—""A telephone, Ron," said Hermione. "Honestly, you should take Muggle Studies next year...”
“The Death Eaters can't all be pure-blood, there aren't enough pure-blood wizards left," said Hermione stubbornly. "I expect most of them are half-bloods pretending to be pure. It's only Muggle-borns they hate, they'd be quite happy to let you and Ron join up" "There is no way they'd let me be a Death Eater!" said Ron indignantly...."My whole family are blood traitors! That's as bad as Muggle-borns to Death Eaters!" "And they'd love to have me," said Harry sarcastically. "We'd be best pals if they didn't keep trying to do me in.”
