Do you have a few minutes? How about 310 of them? You'll need that many to watch all 310 (as of this writing) classic, and not so classic, TV show intros listed over at Net Notables.

Originally, the list only contained 101 intros from shows that aired from 1989 and below. But, as commenters continued to ask where their favorite intro was, more and more links were added. Most of them link to videos on YouTube, which means the five hours and 10 minutes you need to view all of the listed items increases exponentially. To give you an example, after you watch the Magnum P.I.introduction that everyone remembers you can also view the first, more jazzy version of the theme.
