Descargar vídeos de YouTube con un bookmarklet

No sé si ya ha pasado la moda de descargar vídeos de YouTube pero mirando nuestras estadísticas para esa búsqueda y teniendo en cuenta que YouTube ha empezado a ofertar la descarga de vídeos en mp4 creo que aún hay mucha gente interesada.

Este método de descarga probablemente sea aún más sencillo que el de usar bajarYouTube.com. Simplemente tienes que hacer click y sin soltar arrastrar el siguiente enlace a la barra de marcadores de tu navegador:
