Looking for a particular YouTube video...

The video is basically this guy pretending to be a scientist who explains laws of physics, such as gravity, but he's way off. He says to "gravity" means "to go around something."
I think the word Science is in the title.

There's another one that parodies string theory, but he says worms instead of strings.

Can anyone point me in the right direction?

Do a search for Cracked: Marvels of the Science. It was a series of videos of some guy trying to explain everything but being really bad at it. He spoke in a very attenborough style. Here (https://www.youtube.com/watch?v=GZ1Fbr02fXQ) is the first video.
