If there was one thing that Frank Longbottom, first year Gryffindor was known for, it was his temporal consistency. It was said – with a good deal of accuracy, that you could set your watches to Frank's movements.

Frank's mother Augusta had trained him to do this since infancy – and Mrs Longbottom had kept any people who she believed would have a bad influence on him away from Frank. The result was that Frank was a studious young man, and spent his spare time doing quieter extracurricular activities than his dorm mates.

Dorm mates named Sirius Black, Remus Lupin, Peter Pettigrew and James Potter. Whilst they didn't share the same behavioural habits, the five got along reasonably well, and the four troublemakers let Frank have his fifth of the dorm to himself without bothering him.

That is, until the first night of second year. James, snickering evilly, removed all the clocks from their dorm, and Sirius changed the time displayed on Frank's watch.

"Wait until he doesn't have the alarm to wake him up." Sirius sniggered.

The four pranksters woke up before Frank's alarm would have been due to go off, sitting on their beds, staring at Frank's sleeping form in eager anticipation.

James checked his own watch and counted down the last five seconds with his fingers

Three…Two…One.

And Frank sat up in bed, stretched, yawned, swivelled clockwise ninety degrees, and sat at the edge of his bed, pulling his shoes on.

"Morning guys." Frank was used to odd behaviour from those four. "New trance technique?"

"How did you do that?" James demanded. "We took your alarm clock away!"

"Discipline, young men." Frank replied.

"But…but why did you use the alarm then?"

"And make you think of me as some kind of freaky clock-man? No thank you." Frank shook his head and picked up his robes. "Besides, watching you guys wake up at six A.M. every morning and try to hide how tired you were from your nightly escapades was far too hilarious." Frank paused at the door to the bathroom. "You know, I expected better from you marauders." Frank shook his head as if in solemn disappointment, and after the four had realised that Frank Longbottom had pranked them for a whole year without them knowing it, James spoke up.

"Marauders? Not a bad idea, Frank. Not a bad idea at all."
