When teaching Harry the rules of Quidditch, Wood makes his ignorance about the nuances of Muggle sport plain for all to see.
"The Chasers throw the Quaffle and put it through the hoops to score," Harry recited. "So - that's sort of like basketball on broomsticks with six hoops, isn't it?"
"What's basketball?" said Wood curiously.
"Never mind," said Harry quickly.
(Philosopher's Stone, Chapter 10, Hallowe'en).
At first this seems like the standard ironic wizarding response to Muggle society. 'Magic is normal, Muggles are weird and so why would any wizards know anything about the strange ways of Muggles?' and so on.
Yet, barely a page later, Wood is shown to not only be aware of golf but to have a whole collection of Muggle golf balls.
"We won't practice with the Snitch yet," said Wood, carefully shutting it back inside the crate. "It's too dark, we might lose it. Let's try you out with a few of these."
He pulled a bag of ordinary golf balls out of his pocket, and a few minutes later, he and Harry were up in the air, Wood throwing the golf balls as hard as he could in every direction for Harry to catch.
(Philosopher's Stone, Chapter 10, Hallowe'en).
If Wood doesn't know anything about basketball then how could he know anything about golf? His basketball comment could only come from someone who was completely clueless about even the most basic elements of that sport. He hasn't even heard of it.
So how did he come to have his stash of golf balls? Is there some magical connection with golf that I'm not aware of? Or is there some way in which Wood may have come across golf balls whilst not encountering basketball?
