So, today I noticed kkmic's signature: Naturally, it's from Blade Runner, the movie we all know and love. (And anyone who doesn't will politely be asked to leave.) But it was only today when it struck me that I've heard the name Tannh?user somewhere else, too... And then I realized, it was here! Gunbuster science class 1 This clip is an omake (a non-canon additional sequence, often humorous in nature) to the first episode of Gunbuster!, aka Top wo Nerae! (To The Top!), an excellent anime from the 80's. It's a 6-episode saga about an alien war, which you really should see, even if anime is not your cup of tea (back then, it wasn't so hermetic). So, to make this a valid thread, let's call it a thread on such intercontinuities between various works... Can you think of more?
