Oh jumping the shark is just a figure of speech about teleision shows. I think it started cause of the show Happy Days, it had gone on for too many seasons and one episode had them like doing some kind of team water skiing in some lake and all of a sudden a shark pops on on the surface and they jump it while waterskiing (I have no idea dude, I never saw it, generally that's what happened. And people thought it was stupid, that the show had gone off the deep end, lost its way. So that's become kind of a figure speech for TV shows that get kind of stupid, lose their way, go over the top, whatever.
