Will is shocked at those of you that aren't hard-core Cowboys fans like he is.
Here he is trying to look super adorable so that you'll convert to being Cowboys fans.
Interestingly enough, it bothers me when parents put political outfits on their kids (just because you're a democrat/republican/communist your kid is also a democrat/republican/communist?) but I have no problem with parents dressing their kids in sports team attire. In fact, I usually find that adorable. What's the difference though, really?
