What's distinctive about June 2?

It's Chris's birthday! Happy birthday to Chris and to anyone else who shares this excellent day for a birthday. Chris, the younger of my two children sons, is now 21.

UPDATE: Chris--who has a summer job at Whole Foods--emails:

Thanks for blogging about me. And feel free to mention that my first legal drink was an Appletini while you're talking about Gwyneth Paltow's baby's name. I've also been memorizing PLU numbers for every kind of apple we have at Whole Foods, so it's been very appley. If that's at all interesting; maybe it isn't.
