Wow, that's actually a very bad line, but in a different way, I don't like anyone calling out an emergency as a pick-up line, just look at how scared she is, it's like he yelled "fire" aboard aboard a passengerjet at 40K ft, just not fun.
Regarding pick-up lines then I don't have any, I wait until I'm introduced by someone else, I guess that makes me very british lol. Ever heard the joke that if two british strangers stranded on an island they'd never talk to each other because british never introduce themselves, only others (ok not sure if that really is british or just a made-up joke but as a joke it's fun and that was all I intended it to be)
