There’s only two kind of guys who wear those shirts: gay guys and big, fat party animals, and Bart doesn’t look like a big, fat party animal to me! -- Homer Simpson
FLG has a small collection of Hawaiian shirts. His favorite is a Tommy Bahama number, but TB shirts get a bit pricey. Most of his Hawaiian shirts are from Hilo Hattie. They are less expensive, but also not as well made. In particular, the buttons tend to pop off. FLG is a good button repairman, so this problem doesn't matter all that much.
Oh, and FLG is a big, fat party animal, not a gay guy. Not that there's anything wrong with that.
