Things I'''ve done today that involve Bob Dylan: 1.) Pretended to like Modern Times. 2.) Rather aggressively not cared about anything he'''s recorded since''this is awkward''1976. 3.) Thought about growing a mustache; caved under the irony. 4.) Watched this new Escalade ad, in which Uncle Bob''toggling between unintentional comedy and death-by-hangover''drives around the desert, freaks out some birds, and brings the phrase ''"senile chic''" to the forefront of fashion minds everywhere. What does it all mean? Well, among other things, that I'''ve had a pretty bad day.
