Quidditch is easy enough to understand.
Each team has seven players. Three
Chasers, two Beaters, one Keeper and the
Seeker...that's you. There are three kinds
of balls. This one's called the Quaffle.
Now the Chasers handle the Quaffle and
try to put it through one of those three
hoops. A Keeper, that's me,
defends the hoops. With me so far?
I think so...what are those?
You better take this.
Careful now, it's coming back. 
Not bad, Potter. You'd make a fair Beater.
Uh oh.
What was that?
Bludger.
Nasty little buggers. But you are a Seeker.
The only thing I want you to worry about
is this...the Golden Snitch.
I like this ball.
Yeah, you like it now. Just wait, it's
wicked fast and damn near impossible to
see. What do I do with it? You catch it.
Before the other team's Seeker. You catch
this the game is over.
You catch this, Potter, and we win.
