OK, I don’t frequent other message boards that often but…
I’ve never seen or heard the phrase “jump the shark” outside the SDMB. Is this a commonly used phrase in reference to a TV show that has outlived its crunchy goodness? Seems to me that there are a lot of people who wouldn’t understand what it means, being too young to have caught Happy Days in its first run, thus never having seen the Fonz on water skiis… (this was the first image that popped into my mind when I first saw the phrase here on the SDMB, so I knew what it meant immediately.)
Just wondering.
