Ever put together a nice long spreadsheet of numbers in Excel that you've pulled from other worksheets, moved things around, totalled different columns for different purposes... inserted the totals from that sheet into a larger calculation... only to find (by freak chance) that an equation was wrong?
Number of curse words = COUNT of people you've already shown your incorrect figures to
Degree of stupidity = SUM of total screwed up subtotals
Reminding myself I'm only human = also being thankful that today is Friday and my boss and coworker have the weekend to try to forget what a twit I am
Erg. Time for a Friday-style beverage.
