DVD Easter Eggs ((SPOILER))

just a fore warning I haven't looked at any of these myself I got them from www.whedonesque.org

Easter Egg #1:
a. Activate the Wiccan subtitles and start watching "Dr. Horrible"
b. Wait for the "Wiccan" subtitles to get going...they soonish say, "Enter @ [a loooooooong number]."
c. The "looooooong number" when plugged directly into Google comes up with an ISBN for Mariah Carey's "Music Box" album. Shudder. But lo! It is relevant. For in the second "Making Of" featurette, the "The Music" featurette, Felicia Day says at some point that she sometimes sounds like "Mariah Carey."
d. If you hit the "enter" button on your DVD remote control right when Felicia says "Mariah Carey," you suddenly see an Evil League of Evil countdown screen, counting down from 5 to 1

Easter Egg #2:

a. Watch the credits for the Making of featurettes.
b. Look for all the yellow letters.
c. They spell out 'Enter at Act 2'
d. Play the movie and skip to the beginning of Act 2.
e. Hit enter as soon as the title comes up.
f. During the countdown, hit '5' and then enter.
g. Watch the HammerJoss.

Easter Egg#3:
a. Go to scene selection.
b. In Act 2, there is a fake chapter called "Moist dries up"
c. This leads to another countdown.
d. Hit '6' and then enter.
e. Watch outtakes.

Unfortunately, you can't rewind or pause the clips. Rewatching them requires going through some of the process again.
