You might be a freight dog if:
You get parked at a jetway, and all three crewmembers go down to take photos to show the guys back at the hub.
You have to climb down the emergency escape rope to talk to the fueler and get your flight plan at an intermediate stop. (extra credit if this occurs AT YOUR HUB.....well, it WAS before-hours..)
You begin crossfeeding off of the other wing after you notice the excessive aileron yoke displacement poking out from behind the capt and FO's newspapers.
You insist the company provide full-sized 8 x 12" laminated plastic briefing, normal, & emergency checklists because you fly east on the outbound.
You know what a tailstand, a gill liner, and a 9-G bulkhead is.
You piss in a "baggage closet" (NO no. 2!)
Your FE panel has a sharpie-marker "fun meter" on it (and it's pegged)
Your aircraft HAS an FE panel.
Your aircraft is over 100,000 lbs and you have "flight followers" instead of dispatchers.
You carry a Leatherman in your flight case.
