Some time back, the folks from Purism sent me a question: "Would you like to record some voice-over for a little commercial we're making?" "Sure," I say. "Why not?" They give me a script, show me a rough cut of the footage, and I record a few lines. Easy peasy. The only problem? The commercial was for something that I think is a really great idea. And, the finished commercial gave me a serious case of the giggles. Yet I couldn't tell anyone about it. I was sworn to secrecy.
