Following Vikster's lead here's some YouTube crazy for you:
Spiderman: I had just about started going to school when this was on DD. I remember singing the theme song with gobbledygook made-up English during kindergarten in front of the whole class! This was when I had just about barely started to understand the alphabet, a full year before I could read a single word!
He-Man: Everyone remembers He-Man. Probably the most memorable intro ever. And I'm sure everyone's parents remember the toys which they had to buy. This version on YouTube is botched in the end though.
Giant Robot: Although the official English translation of the name is Johnny Sokko and his Flying Robot everyone from India who got DD2 in the '80s remembers this as Giant Robot. The high point of this show used to be all the crazy monsters (and the crazy homemade names we would come up with for them.) Memorable ones were the Eye Monster, the Ball Monster (which was a rolling ball with spikes it could stand on), "Sandwich" (which was a monster which could split into two pieces and sandwich Giant Robot), and of course the Other Giant Robot which was more powerful than our hero but couldn't stand up for some reason. I'm sure everyone remembers doing the steps - swing arms left ("kachink"), swing arms right ("kachink"), swing arms in front ("kachink"), load finger missiles ("chink, chink, chink" etc.), fire!
Switching gears from the '80s to the '90s (or rather from Before Cable to After Cable which I'm sure is the best way to categorize Indian television), here's some Prabhu Deva dancing to some kickass Rahman.
Chikku Bukku: I remember the first time I saw this video I was simply dumbstruck. It just seemed impossible to dance that way and yet the dude was doing it! I don't think I've seen better dancing anywhere else actually. And of course the most frustrating aspect of this video was how little airtime it actually got.
Urvasi Urvasi: After Chikku Bukku, Prabhu Deva was famous (the lone picked-on Tamilian in school made sure of that actually!), and when Kadhalan was released (as Humse Hai Mukabala in Hindi) everyone knew who he was. I prefer the dancing in this video to any other in Kadhalan.
And to finish you off on a happy note, some psychedelic trip-hop from the 2000s
Nice Weather for Ducks: I discovered Lemon Jelly completely by accident. I was watching Eurodance videos at viva.tv (I miss Eurodance!) when I stumbled upon this gem of a video. Watching it once is all it takes to get hooked. (And don't blame me if you find yourself singing the chorus in public.) (All you engineer geeks will also notice that it stretches the video codec to its limits and then breaks it completely!) This is some of the happiest music ever!
