Ok I know there's no such thing as "too long," but humor me!  I've had 2 of these moments so far & am sure other have as well.

...you glance down at your tile floor and think, "game spaces!"

...you stand up after using the 'facilities' and expect it to flush automatically. ;-)

Here's another one:  you go to use your briefcase, and find all sorts of stuff you just threw in there during GenCon.

I'll be "unpacking" for the next few weeks . . .

... someone mentions McDonalds and you think you can just go downstairs for it, or Steak & Shake and go across the street.

... you forget you have to drive to get places.

Some of us at the GAD party did the same think looking down from that 20th floor balcony at the cement below. We were assigning cover to people walking, movement penalties, etc.

I have two. 

You come home from work that first day after the con and wonder why housekeeping didn't make the bed or give you clean towels.

One early morning, you roll over and look that your bedside clock and realize that you have a game starting in 15 minutes and then wake up completely to remember that you work 2nd shift.

You flip through the channels and misread Nascar for Nascrag.

When you give the details of your awesome assasinations in games, out loud, in public crowded places and someone looks at you funny...

After staying up far too late Thursday and Friday for different events, on saturday morning I was pushing my son in his stroller and I saw him drop his bottle.  I was looking for it on the floor and couldn't find it.  It was because someone had already picked it up and was trying to hand it to me but in my sleep deprived state I didn't notice. When I finally did they were just like "we are all kinda there right now, third day of gencon after all" 

Murphoid:

 " third day of gencon after all" 

Wasn't this on Thursday? Doesn't GenCon start on Tuesday now?

...you feel the need to put a Change of Address in for your Gen Con hotel.

• You wake up excitedly, planning to drop off your child at the "Training Area," so you can go shopping.  
• You roll pecentile dice to calculate the tip for your waiter/waitress.
• You still expect that everyone else around you knows the Geekology you are speaking.
• You call anything that you find free....SWAG!  Be it pamphlets at the Dr's office, grocery ads, whatever---it's FREE and you just have to have it!! 

WildeEnchantress:

• You roll pecentile dice to calculate the tip for your waiter/waitress.

Ummm How bout1d8+12?  With percentile you could end up tipping 100%, or 1%.  If you tip one percent don't go back.  They'll touch your food or something.

...you find yourself sad that men walking around at work today aren't wearing Utilikilts!

You know you've been at GenCon too long when...

... you decide on the very last moment that you don't want to go to your friend's party, and start wondering if you'll make it in time to the HQ and get a full refund for the tickets.

... you've developed an Excel Macro that takes the Gen Con event spreadsheet and suggests an optimal scheduling for your interests

... you come back to the office from Gen Con, with a plush Cthulhu for your desk... and your co-workers don't bother asking about it anymore

 ...when no one understands or cares that you're the Iron Dungeon Master 2008 champion. 

...when on your easy to work, put your tiny dice set your pocket 'just in case' 

....when you wonder why your house doesn't have giant banner of dragons of eles with D-cups

...why the restaurant has sports on the TV instead of 300

. . . when you are walking through the parking garage you park in at Wayne State University in Detroit, and immediately recognize a car's license plate as being from Indiana.

Ripley:

...you find yourself sad that men walking around at work today aren't wearing Utilikilts!

Oh man... I love those Utilikilts. I wish you men would wear them everyday! Guh! 

Glory:

Oh man... I love those Utilikilts. I wish you men would wear them everyday! Guh! 

I'm not wearing a normal kilt, let alone a utili-one!  Invent me a utili-karate gi and we'll talk, Carm.

 You know you've been at GenCon too long when...

 you start moving toward the funk rather than away from it.
