The Mega64 Crysis skit, where is it?

I'm going insane trying to find this. So my ADHD brain keeps repeating the "this is what happens when you put crysis in a cup" scene and i wanted to watch the full video as a result, but after an hour I'm trying to search for it I cannot find it. I thought it was its own video, but I'm guessing I was maybe a part of a larger video that my stupid old dinosaur brain can't remember. Can anybody help me try to find this particular scene and what video it's part of?
