T-shirt: Chairman Mao sez RTFM
This t-shirt makes punny nerd fun of Mao's red book and RTFM ("read the fucking manual" in geek parlance). The Chinese characters say, more or less, "closely following Chairman Mao through strong wind big waves and advance forward". Link to more info on tian's blog, buy the shirt here.

I tried to purchase the shirt from your link, but it's no longer on their site and they said they no longer carry it. However, I found it at Zazzle

My few friends who "get it" find it really funny :)
