Happened in a CSI: New York episode too, I have a feeling they might have referenced a real-life occurrence in that as well.

The scouting guides used to have all sorts in - did you ever see the QI where they were talking about what it says to do as a scout if someone is attempting to commit suicide on the railway? Jump on the line yourself and hold them down with your body whilst the train passes overhead apparently. Yeah, right. I think maybe they got "Scouting for boys" confused with "Scouting for John McClane" actually - yippie-kay-aye!!
