Working on Fridays

I'm am currently sitting at my desk where I work typing this. Of course, this not what I'm being paid to do. Why is it that I NEVER want to work on Friday?? I'm extremely cranky on my drive in and I feel like I can fall asleep at the keyboard. Fridays are supposed to be easy days but they aren't. I wish we could work four 10 hr days and have Fridays off. That would be awesome. Well that's all I have on this.....I just wanted to have a random rant. HAPPY FRIDAY...........
