Now THAT was funny.
Once again, you have to be touching the regular running rails and the 3rd rail itself.

For example, in theory, you'd be safe jumping on it with both feet. It'd probably be wise to practice on a dead rail first, though.""As are the non-dead birds that sit on high-voltage lines. When one of those non-dead birds chooses to put a foot either side of an insulator, though, they become very surprised-looking fully-dead half-birds very very quickly!"
I know how electrical current works.
