A/N: thanks for reviewing. You all seemed to want me to write ore so here you go. Please R/R.

Black and Lupin emerged from the tunnel under Honeydukes. They were here on a mission to get tricks to annoy Snape. Lupin stuck his head through the trapdoor, "Come on it's clear" he said motioning to Sirius to follow him. The pair snuck out of the trapdoor and headed out towards Zonko's.

"What are we going to get anyway?" Lupin asked.

"I don't know yet but it will come to us when we get there. I wish we'd have had more time to plan for this." Sirius said.

Back at Hogwarts Harry Ron and Hermione were heading off to their Potions lesson. Sirius and Lupin hadn't returned yet. "Can you imagine Snape's face if they are late for his lesson." Hermione asked.

Ron and Harry were doing just this and they burst out in a fit of giggles. They took their seats inside the class and waited for Snape. He came and Black and Lupin still hadn't arrived.

Two minutes later they slipped in through the door and a second later the bell rung. Snape who was obviously looking for an excuse to give them detention wore his familiar loathing look.

On the other side of the classroom Malfoy was wondering how he could stir trouble with the newest members of Gryffindor . he whispered something to Crabbe and Goyle while Snape was calling the register. Black had already taken his godson's dislike for Malfoy and had named him as their victim.

The lesson started and it turned out that they were studying different kinds of appearance changing potions for the next term. The first potion was a fairly 'easy' one which could make people grow extra hair or change hair colour depending on the amount of seaweed in the potion.

Neville had already decided that his potion would probably have disastrous results and had warned Black and Lupin about this. The reply they gave had been a strange one to Neville, "It doesn't matter nobody will have time to make any potions."

Harry and Ron knew what they were talking about and were looking forward to the trick even tough they didn't know what it was.

Snape had written the ingredients to the potion on the board and the class got down to work.

Black dipped a rubber chicken that they had bought in Zonko's into the potion. It became covered with hair. He then muttered a couple of words under his breath and the chicken sprang to life. It ran around the classroom shrieking and many of the classmates were unable to retain their laughter. Lupin picked up a stone they had brought into the classroom with them and threw it into Malfoy's cauldron. The potion splashed all over many of the Slytherins and soon they were covered with hair down to the ground. The chicken which had been running rampage around the classroom bumped into Snape causing him to go flying. He narrowly missed falling into Patsy Parkinson's cauldron and instead landed in a puddle of potion which rested on the floor of the dungeon. He stood up and the so far unscathed Gryffindors burst out laughing to see that Snape had grown a bright pink moustache.

Snape marched out of the classroom and to the transfiguration classroom where McGonagall was teaching a group of first years how to change matches into needles. None where having much success. When they saw the moustached Professor walk in the burst out laughing, even McGonagall had trouble stifling her giggles. When Snape told her the story of what had happened to his class she quickly dismissed her own class without giving them homework (There's a first time for everything) and went to see the rest of the class. By now some of the pupils had gone down to the medical room but some still remained. Malfoy was one of these and he had hair all over his body as he had been worse hit.

The situation wasn't made any better by the fact that the first years who McGonagall had been teaching had found a group of seventh years (Who should have had defence against the dark arts) and brought them to witness the class.

Two hours later after everything had been cleared up Black and Lupin were in Dumbledore's office.

"Now I don't want to hear that it wasn't you because it was." He said calmly, "But I thought you would have been more mature than this."

"It was a one off. Just to let everyone know we're back." Black said.

"You can't honestly say you weren't expecting it." Lupin added.

"Not really." Dumbledore replied, "You will have detention tomorrow night, and you will behave for the next week." Sirius and Remus looked shocked at this latest instruction. "It won't kill you. If you don't you will be facing expulsion."

They left Dumbledore's office after promising they would behave.

As it turned out they wouldn't have enough time to misbehave, the whole school was treating them like heroes for what they did and they were enjoying it.
