Yvonne Craig, who played...

...Batgirl on the hit 1960s television series Batman, died at age 78.

78? Really? Let's see, that would have made her about 30 when she debuted on the show in 1967. I guess that's right. (I must be older than I thought.) Anyway, I had pretty much lost interest (like everyone else) by the time Batgirl showed up, but it's worth noting her passing.
