It Doesn't Ad Up

I cringe every time I drive by a billboard that has the "Nobody's Gonna Lay A Finger On My Butterfinger" ad.  It's a horrible line for a lot of reasons, but worst of all is the non-rhyme which they seem to believe is one.

I'm not expecting Cole Porter, but certainly they can do better.  I mean a near-rhyme I can handle (okay, I cringe a little, but you can't expect much more these days), but rhyming "finger" with "finger"?  And the second one isn't even stressed the same!

I guess this campaign will have to join the other identity problems, "you've got a right to chicken done right" and the all-time winner...
