One of the Earth's most beloved books and mini-series celebrated a big birthday today.

Douglas Adams' Hitchhiker's Guide to the Galaxy was first published 30 years ago today. The wildly imaginative and funny science-fiction novel spawned four more books, a radio series, a text based video game and a cult classic British mini-series. It also spawned a big budget Hollywood remake that shall not been mentioned again in this post, so there.

In honor of this momentous day for sci-fi humor geekdom, here is the iconic opening of the original BBC mini-series originally aired in 1981. Pour yourself a Pan Galactic Gargle Blaster and enjoy.
