"We'd like to dedicate this next number to a very special woman. She's a hundred years old, and she weighs over two hundred... tons." "This enourmous woman will devour us all! Ahh!" "Er, I meant the statue..."

~~ The Simpsons, Barber Shop Quartet episode



Or in my case bug!
I put some papers down, turned my back for less than 30 seconds and turned around to find a silver dollar sized beetle sitting on the same papers!! It's winter! No idea where this monstrous creature came from!  It may have had wings. It was up on the desk!  No idea how it got there. 
I went into flight mode and tried to make a break for it...but I needed to fax the documents it was currently sitting on. So I beat the bejeebies out of it with my shoe and stomped on it a few times to be sure.
I'm still shaking!  If it was flying I would have handed over the keys to my office and just gone home.
Unfortunately, it left bug guts on the document...and I had to go and request another original to file.
This is just not my week.  Everytime I see somehting out of the corner of my eye I need to check that it wasn't a scout beetle from some colony that's taken residence up in my office and they're now planning the first wave of their assault to take over the world.
