Do you know of the Wadsworth constant? It says you can skip the first 30% of a YouTube video without missing anything important, because, as a rule, the interesting stuff starts at roughly 30% in. Well YouTube has now recognized and implemented the Wadsworth constant as a feature. Just add "wadsworth=1" as a parameter in the video URL, and the video will start playing 30% in, sparing you the boring intro. Try it.
