Doesn't the term 'jumping the shark' refer to doing something outlandish in order to give life to something that is ultimately dead? I always thought it was named after that moment in Happy Days when the Fonz waterskied over a shark in a desperate bid to get a bit more mileage out of an ailing show. If that's true, then 'jumping the shark' might still be the most perfect way of describing McCain's appointment of Palin.
"The Fonz says Vote McCain"
