I also really like the idea of a hooded sweatshirt - it would at least fit into the monk theme. Of course, if your office environment dosen't really allow sweat shirts, we'd also have to offer polo shirts or something like that, but for the main thing a hooded black shirt would be "my thing" - or maybe a hooded red shirt.

As for the obfuscation code, I'd really like the obfuscated code embroidered (or however that's spelled) on the shirt in the same color as the shirt color, so that you don't notice the code at first glance...

Now we just need to see if thinkgeek does manufacture them at reasonable prices
