Cheaper than the Vomit Comet

I have to find a really big swing set and try this. Some of Randall Munroe's xkcd webcomics are really funny, which proves beyond a shadow of doubt that I'm a hopeless nerd. I was also home reading a book on Saturday night. He also has a blog (or blag). I probably laughed out loud at this Schrödinger one. Yes, quantum comics.
