What do airline passengers do when they're stuck on a runway for hours?

Mainly complain. Please remember the flight crew on the plane with you usually has no control over the wait- they are stuck there, just like you. I travel a LOT, and sometimes there IS a hold due to weather, air traffic, etc. I usually read, play games on computer, get some work done, make phone calls, have a snack, and nap. Much better than whining.
