Max and I made some git t-shirts spoofing a well-known dairy campaign, promoting git, the fashionable source control system:

and an alternate style:

Go ahead, buy a git t-shirt, you know you want to!

PS: as has been pointed out to me by a few friends, I don't use git. I know this. But "svn code?" isn't a good slogan!

PPS: the Zazzle terms of service request that I state that these shirts were made "in partnership with Zazzle.com".
