I'm not allowed to say what this shirt actually says. If you are a "Bleeping Nerd" (hint) who knows binary computer language without a chart, then this shirt is for you.
If you don't understand it, then buy this for your "Bleeping Nerd"(hint) of a friend.
The shirt says "If you can read this, you are a 01100110 01110101 01100011 01101011 01101001 01101110 01100111 00100000 01101110 01100101 01110010 01100100 ...and I am too!
