Here is something you should watch, presuming you haven’t already. It’s called “Look Around You”.

Actually, if you have already watched it, watch it again. It’s good for you! Education is key.

Here are links for the rest of the series:

Water Germs Ghosts Sulphur Music Iron Brain

And the pilot, Calcium (1, 2)

There were apparently later series, but from what I’ve heard and seen, they’re not really worth watching. They must have used up all their funny on the first ones.
