I have found out that quite a few people share my 'only able to get out of bed if the time on the alarm clock ends in 0 or 5 strangeness.'
But I have taken this a step further.
~~~~~~
I log on to the computer at work.- 'Oh for Fucks sake!'
Colleague, concerned.- 'Whats up? you OK?'
Me- 'Yeah, but some twat has left the volume of this PC at 37.'
Colleague- 'Er, So?'
Me- It's a prime number. I'm going to have to change it to 35 or 40 now. Why can't they just leave it at a proper number like normal people? I'm all tense now.'
Colleague- 'You what?'
Me- If it was one less, 36, that would have been OK because it's a square number. Fucking idiots.'
Colleague. 'You're strange.'

Same...
Although mine has to be multiples of 5, I also do it with TVs and stereos. We've just got a new TV in our apartment but there's an ever so small delay between pressing the volume button and the TV responding which means several minutes of frustrated jabbing at the up / down volume button to get it perfect only to have my girlfriend come into the room, complain she can't hear it and turn it up. Cue another 5 minutes of messing around

OPPOSITE!
For some reason I will only set my alarm for anything other than a number ending in 5 or 0. I work nights and my "wake up" alarm is set for 01:36 and my "get up" alarm goes off at 01:48.

Alarms that had a 9 minute snooze...
WTF? why not 10 minutes?
