oh another time me and my two roomamtes coincidentally all booked the same flight to Seatac(then they go to hawaii, me to CA), so we drove to the airport together.  Well i hadnt smoked much at all in the past few weeks due to schoolwork and such, so my tolerance was pretty low.  Well we stopped at a club and picked up an 1/8th, which we then rolled into a blunt.  but we also put a fat ass snake of hash in the blunt.  we hotboxed the car and then 5 minutes later we were dropped off at the airport.  HOLY GOD was i stoned.  like incoherently, nother world stoned, as were my roomates.  i proceed to walk directly into a glass window on the outside of the building becuase i thought it was a door(got some bad looks for that).  we finally get our tickets and go through security, where the security gaurd decides to have some fun with us, and starts asking us the most random questions ever(do you prefer eggs over easy, or boiled?  what two colors make green?), then jokes that he wont let one of my roomates on because he doesnt believe he is from hawaii(dude is 1/2 hawaiin 1/2 samoan).  he is doing the whole "im joking, but seriously im not, im just fucking with you, but actually you cant go through".  we were way too confused at this point.  we end upgetting to our gate and sitting down and proceed to watch a solid hour of And1 mixtapes, mwanwhile they were calling our names because the plane was about to leave(we were the only ones left in the gate area and fit the names perfectly).  all of a sudden i hits one of us that they had been calling our names for the last 5 minutes and we bust out laughing and proceed to board the plane where we had to walk all the way to the back of the plane throught he packed cabin, reekingg of MJ smoke, laughing and grinning uncontrollably the whole time.
I have also had to ask a ticket seller to help me out with the boarding pass kiosk because i was still so drunk from the night before that i couldnt read it.
basically, as long as you arent a danger to others(ie aggresssive, falling over) airlines dont care how fucked up you are.
