Staff duty horror stories?

Just wondering if anyone out there would like to share a horror story with me. I'm currently pulling a 24 hr. shift with the world's most obnoxious staff sergeant. He keeps leaning over my shoulder and asking me what I'm doing (he just left for a couple of secs). Anytime I play a game online or on my laptop he gets all excited like, 'ooh, ooh! whatcha doin?!' The worst part is he doesn't even have to be here right now. His 1SG told him that he only has to be here for security checks (that only needs to be done once a night). He's only hanging out because he wants a comp day tomorrow. While watching tv tonight he made a comment about every single thing happening. My lack of eye contact and rude facial gestures don't deter him at all. I know he's not hitting on me or anything. (He's happily married, which he brought up immediately after asking me, "weren't you married before?", "why didn't it work out?"). The only thing to get me through will be witty humor. HELP!!!
