I don't even set the clock anymore - always up before it would go off....
Here's a funny one for you Bob.
Back in the mid 70's I had a "mechanical" digital (the kind that the numbers were on little "cards" that flipped over) and it woke me up most days with a horrid mechanical sound.
When I first got "Wish You Were Here", that same sound woke me from sleep with my headphones on......(the sound at :05 and :24) On Welcome To The Machine.

but it wasn't time for my alarm, it was 11 at night!!
