A/N: Aha! I was in the car and I got this idea.. Just a one chapter quick fic. It's not supposed to be good, I just need to get it outta my head. Feel free to review and flame tho! WELL! Here ya go- "OPPOSITE DAY!"

James Potter woke up on a lovely day in March, not knowing what await him. He stretched and looked at the calendar.

"Oi! Sirius!" he poked his best friend, Sirius Black, who awoke and asked, "What, Prongs?"

"It's-I mean--- I don't mean. AW forget it!" He thrust the calendar under Sirius' nose, pointing to March 16. Sirius grinned- it was Opposite Day, named March 16 by the Marauders in 1st year.

Opposite day was taken very seriously by them. It was a fun time to confuse teachers, fellow Gryffindors, Slytherins, and Peter.

"Hey- Remus!!" Sirius knudge him, and showed him the calendar.

"Yes! I mean- No!" Remus cried.

Later at breakfast.

"Goodbye Lily!" James greeted the red headed Lily Evans.

"Er; whatever James." She replied.

Sirius sat down next to Bella, Lily's best friend.

"Au revoir! How aren't you doing this ugly night?"

"Sirius, did you bump your head on the chandelier again?" Bella asked, slightly amused.

"Yes!" Sirius replied cheerfully.

On the other side of the table, Remus sat down next to Peter, who jumped when Remus said, "What's down, Wormtail? Anything old I shouldn't know about?"

"I-I'm afraid I don't understand you Remus."

"Bad!" Remus said, helping himself to some toast.

James took a bite out of his English muffin, and said to Bella, "Ya should no this Bella, but my enemy Sirius over here doesn't hate you!"

"Um. Okay James, I think I already knew that." "Are you sick?" Lily asked James.

"Yes!"

In Charms.

"Bad evening, Professor Flitwick!" Remus said happily to Flitwick as he took his seat.

Flitwick, who was looking for something in a stack of papers and wasn't really paying attention, replied, "Same to you, Mr. Lupin."

"What the heck is WRONG with you three???" Bella hissed.

"Something!" James shouted.

"Well THAT'S obvious." Lily muttered as she took out her notes.

Professor Flitwick stood on his pile of books and told the class, "Pop quiz today!"

The class groaned, except-

"Yay!" Remus, James, and Sirius squealed.

Flitwick handed out papers. James, Sirius, and Remus nodded to each other. On James' paper, under where is said "Name:" he wrote "Remus Lupin." On Sirius' paper was "James Potter" and on Remus' was "Sirius Black." (A/N: Hey I know that's not there opposites. but. I don't care^_^)

In the middle of class, Sirius stood and shouted: "I'm not done!!!"

"That's all right Mr. Black!" Flitwick said, bewildered.

"Oh, that's not okay, then." and he sat down, while Flitwick scratched his head.

Later--- at Lunch.

"Please don't give me the marmalade," Remus said to Lily politely.

"I won't don't worry." Lily said, studying her History of Magic notes.

A moment later, Remus repeated, "Please don't give me the marmalade, Lily!"

"I'm NOT giving you the marmalade, Remus!"

A moment later, "Lily, I asked you NOT to give me the marmalade!!"

"FOR THE LAST TIME Remus!!! I'm NOT giving you the stupid marmalade!!!"

Meanwhile, with James and Sirius.

"Hey- Sevy!" James called to Snape, grinning friendly-like.

"What do YOU want- Potter," he spat.

"I wanted to ask you if you wouldn't please stick your head in a bucket of frog spawn."

"Don't worry, Potter- I;m not that stupid. Why do you care, anyway?" He said, confused.

Sirius waved, and they walked back to the common room skipping.

Once again-Later. in History of Magic.

"Now if you would please open your copy of History of Goblins, we can get started." Binns told them.

"No." Said James.

"Excuse me, Mr. Potts?"

"It's not Potter, ma'am. I said 'no'."

"Detention, Potts, for being a smart alec."

"Ooo, dats bad!"

Binns ignored him and went on, reading page 14 of History of Goblins.

A long and boring half hour later, Binns said, "Please pass your homework to the right hand side of the room, where I will collect it."

"Er- Mr Potts? Mr. Luppino? Mr. Blacking? Why may I ask are you passing your papers to the left, when I clearly stated right?" he asked, annoyed.

The three received a detention after the long argument that followed.

You know the routine. Later..(a/n: hehe) at Dinner.

"It was a very unsuccessful day, wasn't it, Padfoot, Moony?" James said while puring gravy on his mashed potatoes. "No, of course!" Remus and Sirius said.

Lily asked, "What is the matter with you three???!"

"I told you, Lily- Something!" James said, matter-of-factly.

"Whatever. Forget it!"

Later.

"I'm not tired!" Remus said as they climbed into their four posters.

Smiling, Sirius asked James and Remus, "I just hate opposite day, don't you?"

A/n: Well Now I will get back to my other fics! Review lol! ~Lily Flower!
