The dreaded 666

Ok so the number 666 has been occurring way too often today.  First, there was the price of my plane ticket $666.00 (So I opted to add the insurance after I saw that!)  Do you think they purposely planned that price?  Secondly, I received a confirmation number for something that I ordered, which showed 666 as the last and only numeric digits.  Lastly, I was just going to check my Twitter account, and at the top of the page it showed that I had 666 new Tweets.  I suppose I shouldn’t be too worried, unless the clock suddenly reads 6:66…
