hm, I don't even know how much I get paid O_O, I check my pay stubs every once in a while, I know I get paid at least 40 hours, if that much gets put into my bank account on pay day then I don't worry about it. If I work some OT, I know my next pay check is bigger but I don't really care :S I treat it like any other paycheck. Same with when I work PRN but I haven't for a few months.
But then again, I only work 1-2 hours OT every few months, I try not to but if company really needs me IE someone is sick, I'll stay an extra hour or two until someone else comes in. Plus I'm expensive to pay OT (company pays twice base rate for OT instead of 1.5) so they try not to give OT to anyone.
