Heh, this may sound very stupid, but it still happened. Funny coincidence, it happened today.
Getting out of philoshophy class, I was explaining to a friend a math equation. I was putting him into context and made the motion of jumping out a window, wich was closed. So, yea, I jump slighty at the window, and guess what, it was broken, so the window popped open and I went out of it. For a sec, I was sure I was about to die, was on the 3rd floor etc. A slip second after I was out of the window I got grab of a metal bar (construction site etc.) Lucky me, I thought my final hour had come.
Biggest adrenaline rush I ever had, best part is the action was in less than a second
