Sleeping in your office

First off, it's YOUR office, who do they think they are?

Oh yeah, Bosses.

Be turned away from your desk working on another computer so when you open your eyes to see the Sales asshole standing there, you stretch, yawn, and say "Meditation Over".

Sleeping at desk, always have glasses on, reading material on keyboard since your head is likely to droop, and door closed so they at least knock so you can look studious.

Full out passed out in your chair with head back and drool forming? Yeah, gonna get fired.

I haven't hit the last one yet, but Dude, I'm on my way.
