P.S. If you don't have "Strollertown" by Jonathan Coulton imprinted on your brain, you're really missing a great stroller tune. I sometimes seriously consider getting a red Maclaren Techno XT because of this song (and I may not be alone in this twisted impulse as Amazon is currently sold out of the crimson version of these sweet rides).
Coulton is a huge favorite in this geek household. We love Code Monkey.
