It's strange sometimes what enters a culture's consciousness to stay, and the Big Lebowski and its characters seems to be one of those things.  Naturally, everyone relates somehow to "The Dude," and truth to tell, if Ben and Jerry's came out with this flavor, I'd very likely buy it and enjoy it, just cause it's Dude food!  After all, I'm a dude, and I need food, and food should taste good, so let's all eat some.  There should be some rum raisin in there somewhere, though.
