Call me a Fanboi, but I think i'll actually have a Visual Studio T-Shirt made, like the one on my Gravatar.

Apart from that, a T-Shirt that just contains the Letters "FCKGW" came into my mind as well, as a hommage of all the PC Technicians who had to deal with customers who did not (want to) understand why you are not able to install Service Pack 2 on their Windows Version.

I have an ancient shirt that reads:

I get mine printed myself. My favourite ones are

/* programmers */
do {
    it();
} while (1);

and one that has my initials in ASCII binary.

I also have one that simply says "THAT SOFTWARE WOMAN" which was how a client once referred to me when he couldn't remember my name, and I thought it was quite a good way to refer to me really :-)

Unfortunately, I'm having trouble finding a pic of it online, but many years ago I got a t-shirt from Urban Outfitters that said "I'm a super-duper programmer". It doesn't fit me now, but my wife still wears it!
