Snape sat outside under a tree by the lake. This was good. He could get some fresh air without effecting his pale complexion. He opened up his book and started reading. He had gotten to the section on various uses of krondle seeds when the ground exploded next to him.
"A little to the left!" some one shouted.
"Aye aye, Captain!" came the reply.
Snape looked into the hole. A cannon ball. He looked to where the shouting had come from. The lake. His four least favorite people were sitting on a raft in the middle of the lake laughing their arses off. No. Only three of them. The werewolf wasn't there. In fact, he was sitting on the other side of the lake. Doing homework, it looked like. Not that Snape cared what her was doing. Snape concentrated on getting the cannon away from the idiots.
"They don't have a cannon," he said looking more closely, "or cannonballs" He magically amplified his voice. He wasn't about to yell. "How are you going to shoot me without a cannon or cannon balls?" he asked.
"We're..." shouted Sirius.
"Good point!" shouted James.
"Magic?" suggested Remus, adequately distracting the audience from the Authoresses foul up.
"Man over board!!"
Peter helped further by falling off the raft and drowning. Well, not really, but he almost drowned. A mermaid, several actually, threw him out of the water onto the shore and emitted a high pitched shriek that can be translated as ,"don't throw trash into our lake."
