Do you know people who say they'll test, review their design, and refactor when they "get around to it?" Well, now I have the perfect response for them:
A Round Tuit!
Yep, it's a Round Tuit. Hand these out whenever you meet someone who waits to "get a Round Tuit" (say it out loud) before they test, design, or refactor.
They're silly and fun! I've got 1,000 of these and I'll be bringing a bunch with me next week to share at the Agile 2005 conference. Come find me and I'll give you a healthy handful to use with your team.
