shirt of Tee

I have found the greatest tee shirt offered by the internet. So many are offered here and there, but so many aren't very good. There are a few good ones, like xkcd has some nice ones in the store.

Ah, the regular expressions shirt... except that the whole swinging in heroically to apply them rather made the comic. And I don't really use them enough so any time I really want to do something fun with them, I seem to have to look up bits.

Ooh, the sudo shirt... even though it always felt like a joke I'd tried before. Odd thing is, the systems I might try it on rarely have the command installed and even fewer seem to have given me sudo permission on the particular command in question.

Hum, the one titled "stand back (science)" is getting there...

This is the greatest tee-shirt on the net. It has a wonderful mix of alienness and childishness and simplicity. Also fun is the related web comic.
