I'm convinced that some people are born with more common sense than others.  In the case of Overtalker, she's one that lacks a great deal of it.  Last week when her computer crashed and the IT Department was in the middle of replacing her system, she starts spraying her entire cubicle with Windex to clean the area behind her removed monitor. 
"What the HELL are you doing?!" yelled the IT Guy, "Are you intentionally trying to electrocute me?!"  Overtalker had sprayed all the electrical cords.  "I was just trying to help" she said.  "Thank you but Windex doesn't help fix computers."
