Every time I go through screening at Dublin Airport the procedure seems to change a bit... at another city recently I went through one of the Full Body Scanners for first time ( oh yeah baby- howdya like my salami?)..came across this TSA video & burst out laughing multiple times..
( if you travel at all, it's worth watching til end)
