Mostly I just wanted to show this video to someone who wasn't a Facebooker and am thinking I can maybe do it this way? It's my littlest brother singing along to the fastest-moving song from Dr. Horrible's Sing-Along Blog.
Turns out it works, so I'm going to upload my other favorite sibling video. This is my sister Elizabeth's deliberately awful pretend American Idol audition. I made her do it for me like six times and kept laughing every time she did.
