How now, brown cow?

Mr. Dub's coworker, Karen, has changed my life as of late by giving me her old People magazines only days after receiving them. Yes, I'm not too proud to beg for celebrity gossip.

The other day, I was devouring the contents of the latest issue, which features Keith Urban on the cover. Now, I don't know much about Keith Urban, except that he is:
a. Nicole Kidman's husband
b. a recovering addict (to something?)
c. an Australian country singer, which is, like, the weirdest concept ever - Was crocodile wrasslin' and digarido playin' not enough for the Aussies?
d. not a cow

But apparently I was wrong on the last point. The minute Miss Dub saw the cover, she started to do her cute cow sound, which includes a muffled, "Mooooo!" and puckered lips. Confused, I looked all over the cover for some sort of bovine reference. Nothing! So I pointed at each picture trying to figure it out. When my finger landed on Keith Urban's face, she instantly mooed. Since then, I've sporadically brought out the mag, and each time Miss Dub breaks into her cow impression at the sight of his shaggy hair.

I wonder if Nicole knows.
