I just brought matches on a plane last week. They have no way of knowing that I have matches with the metal detector and although they 'felt up' my wife and baby, they didn't get their hands in my pants to find the matches...
As they were busy 'searching' my wife (who was holding the baby) they complained that all of our stuff was clogging up the conveyor belt and asked me why it's taking me so long to remove everything. I told them it's because of my terribly suspicious looking baby and said they'd better make sure she's not a threat cause she seems reaaally dangerous......
