The lighter side ... parenting as a scientist

There's a wonderful series of bibs for babies of scientists and other very smart people. Very simple, just a few words, but very creative. The link is here, the recommendation is Marginal Revolution's, and my top ten below the fold:

• Schroedinger's diaper: isn't full until you check it.
• Dependent variable
• My comparative advantage is poop
• Demand function (arrow to mouth), production function (arrow to diaper)
• (for your twins) Test          Control
• Increasing entropy*                            *entropy= poop
• Figuring out world ... 30% complete
• Updating priors
• Longitudinal Study
• Positive Externality
