Today is Cow Appreciation Day at Chick-Fil-A. Wear a cow costume to any of the chain's restaurants and you get a free meal. What -- you don't have a cow costume? Chick-Fil-A has a kit you can download.

This event reminds me of when my son was 2, and had an adorable Holstein Halloween costume. He was very fond of it even after Halloween had passed. One day, when we were going to see the "Curious George" movie, he decided he just had to wear it. To the theater.

Two-year-olds aren't capable of embarrassment. Instead, he waved at everyone who pointed to or waved at him. After tucking his tail behind him, he gleefully munched on his popcorn and watched the movie.

Costumed cows aren't always benign, of course -- they can be "mad," as in this photo of vegetarians protesting meat consumption in Britain. But the larger point is how great it is that when you're a kid, you can be anything.

And become anything.
