Why don't I have one?

As I look around my work environment this Friday morning, it seems an innumerable amount of men are wearing "hawaiian" shirts. And so I ask myself, "Why don't I own one?" I won't go into my answers, but most of them center around the fact that I need no additional help being uncool. The other thing I notice is that there seems to be an age limit on who can wear a hawaiian shirt (and untucked, at that). The average age appears to be mid to late 40s. So I guess maybe in 15 years I can get one. I wonder if WalMart will still be carrying them...
