I had a roommate who said this to me once when I asked him what he was making. The pause before and the matter-of-fact way he said it made it one of the funniest things I have heard. This comic doesn't quite capture that moment, but it commemorates it pretty well. My roommates were completely vulgar, and I eventually fell under the vulgar spell while I was living there and became known for my vulgarity at work. I don't live there any more, but I'm still pretty vulgar.
The chainsaw-in-the-kitchen gag is a nod to the old NES game Maniac Mansion.
