TITLE: What's your best "that could have been a scene in a movie" story?
POST: Whether it involved you directly or you just witnessed it, tell me about a time when something happened that could have been scripted for a movie.

For me, it was when I was living in South Korea teaching English ('05-'07). I was in a band, and we were playing shows pretty much every weekend, mostly in our hometown (Cheongju) or up in Seoul.

One club we played in Itaewon (Seoul's foreigner ghetto - adjacent to a giant US Army base) was called the Big Electric Cat. At around 2-3 a.m. we were in the middle of our second set when the MPs came around checking for soldiers breaking curfew. As soon as they walked in the door, a girl who was up at the front jumps on stage and asks if we could play Sweet Child O' Mine, which we'd never played in concert because neither of our (male) singers could sing Axl.

She was hot, so our lead guitarist just starts the opening riff, and we played through the entire song. If not without a hitch, without any major screw-ups at all, and she sang like a beast. In short, it was great.

By the time we were done, the crowd had thinned slightly because the MPs had caught their targets and left with them. After we finished the song and took a break between sets, we found out that our guest singer was also a soldier, and the whole thing had just been a hail-mary ploy to stay out at the bar and avoid being hauled back to base by the MPs.
TL;DR: 
A girl jumped up on stage and sang a song with my band to avoid being dragged away by Military Police for breaking curfew.*
