A/N: This is only my first story, so go easy on me.
James, Sirius, Remus and Peter sat relaxing underneath their favorite tree by the lake, when James noticed a group of giggling second-year Hufflepuff girls walk past, and couldn't help but stare.
"Keep your eyes in your head, James," Remus said, without even looking up from his book.
"How did you know I was staring at anything?" James asked.
"Please," Remus said, annoyed, "I didn't need to. I simply heard those girls giggle and I've known you since first-year."
"Didn't have to get moody, Moony," James said in a taunting voice. "Is it your 'time if the month?'"
Remus proceeded to throw the biggest stone he could find at James, although it wasn't much bigger than a pebble. The Hogwarts Grounds didn't really have any large rocks, but nobody was sure why.
"Come off it," Peter said. He never let them have any fun.
"Wormtail, you never let us have any fun!" James exclaimed, "And you're no better, Padfoot. You're always in a broom closet, having fun enough for all four of us!"
"I don't think my shenanigans in a broom closet are any of your business, James," Sirius said sleepily.
"Hey, James, I just realized something," Remus said, "you're the only one of us without a clever nickname. We have to think of one."
"Didn't I tell you? I've taken the liberty of giving him one," Sirius said, suddenly wide awake.
"Yeah? And what's that?" James asked.
"Prongs, of course," Sirius said matter-of-factly.
"'Of course'? You say it like it's obvious. Why that name?" Peter asked.
"Because whenever girls walk by, that's what he gets! A prong!" Sirius said, and laughed hysterically.
"It does suit him," Remus said, and suppressed a giggle.
James objected, but the name stuck. And so named were the marauders; Wormtail, Moony, Padfoot and Prongs.
