Lost your mojo?

Nothing can be more frustrating for a writer than to be stumped for an idea.  This is not normally a problem for me but today I just feel like I'm in a rut. On a typical day I could write for four straight hours and never realize that so much time had passed.  Today...nothing!  It's like I have this bottomless void in my mind.  I'm having the biggest brain fart of my entire life!  It's kinda creeping me out to be honest!  I guess it's a good thing I had already planned on spending my evening editing my manuscript. 

So what do you do when the words simply won't come?
