Bludgers
"James," said Sirius to his friend as they sat in the hospital wing after a quidditch match because they had BOTH broken a bone.
"Aye?" replied James.
"Bludgers are a lot like cannon balls," Sirius said adjusting the sling that his arm was in.
"You're right," said James, sitting up straight, "next time we go out on our pirate ship we should take bludgers to throw at Snape."
"Exactly," said Sirius nodding sagely.
Luckily for them, and unluckily for Snape, Madam Pomfrey wasn't in the room to hear this dicsussion.
End
Ok, short and stupid, I know.
