Anyone else have a story of having a ridiculous amount of something you think you will never go through and in one day, POOF, gone. 
I had three serial cables go bad in a day, when I needed them to access a console port on a switch.  My customer had a good serial cable, so I knew that my serial port and settings were correct.  
I went for years without any sort of need to change a tire on the side of the road -- heck, I went through two entire cars with 125K miles each on them without that.  Then in April '09 I lost two tires at the same time in my new car.  That was an expensive day.
Another time, I went through all the spare server memory and several spare servers one night about sixteen years ago trying to get a server back online before the busiest day of the year.  I had a humongous collection of server and workstation components, but for all of the tens of thousands of dollars of stuff, we couldn't put it together to make a working Novell server.
My boss wouldn't have fired me so much as executed me and left my head on a pike as a warning to others if we hadn't gotten back online.  I called one of my staff after eight continuous hours of troubleshooting, at just about midnight.  I'll call him J.
cm: "Hey, J.  I hear that you got a new PCI SCSI card for your gaming PC."
J: "Yeah, it's really neat!  It's an Adaptec blah de blah..."
cm: "I want it."
J: "You can't have it!  I got a great deal on it and --"
cm: "GOD DAMN IT J!  I WILL BUY YOU ANY SCSI CARD YOU WANT!  IN THE MORNING!  WHEN THE STORES ARE 
OPEN!  I NEED YOUR SCSI CARD 
NOW!"
J: "Oh, sure, no problem, I'll pull it out and bring it in to the office right now.
There's a reason that my nom-de-website is "chaosmagnet".
