http://www.jumptheshark.com/jump the shark is an expression getting lots of ink these days, and I'm curious as to whether the concept could be considered a meme.  it's almost like the straw that broke the camel's back, or the one-hundredth monkey...  I'm seeing these waves, trends that push forward and then fall back as the shark gets jumped, as the straw gets placed.  as I write this, I think the hundredth monkey idea doesn't quite fit.  but it's getting me thinking. again, I can't quite 
feel this. or maybe I can feel it, but can't quite touch it...
I'll shutup now.
oh, and Bill, probably.  response to external stimulus could qualify as a meme, no?
