If you haven’t heard of this yet, allow me to introduce you to an excellent waste of time: Dr. Horrible’s Sing-Along Blog
is an internet miniseries in 3 parts that lasts only until Sunday.

Starring Neil Patrick Harris as Dr. Horrible, it is mucho entertaining.
It was developed in response to the writers’ strike. If you want to know more about that, read the MASTER PLAN on the home page at http://www.drhorrible.com

Otherwise, just watch Act I and Act II when you have some time to be entertained.
