Loved this post at Rosenbaum's site. http://ronrosenbaum.pajamasmedia.com/2007/01/26/the_geico_caveman_finally_jump.php
From: Comatus (look it up) :
I am one of several million Americans who are regularly mistaken for the cavemen. I'm getting to feel rather close to them. Now, the credit card out-of-work plunderers--*that* was "victimless ethnic" humor, and could have been filmed on Main St in my town, without extras. I invited a "tribe" of people over for Christmas dinner, and served roast duck with mango salsa--then had to explain the joke.
