I don’t think it will ever not be funny flying wearing kilt.
I normally get stopped at quiet airports with old-fashioned metal detectors because my kilt has built-in buckles that cannot be removed.
Today, while getting padded down, a security bloke lets the poor woman tasked with doing the pat-down know to check under the kilt, getting all embarrassed when he learns I understand Danish perfectly well.
Lots of laughs were had all around.
