Time saver

I'm staying with my friend John tonight, and he just brought me an alarm clock for my makeshift living room bedroom.

He was setting the time on it for me, so I told him the time: 12:54.

He started pressing the minute button over and over to get it to 54, then rolled his eyes, sighed, and said,

"I should've waited six minutes to do this, it would've been one button."

Meaning, only the hour button: 12 a.m. Bam. Done.
