Wow, this animation looks like it really was made by someone drinking a lot of alcohol while making it. It's not funny; anywhere there seems to be a "joke" the video relies on the viewer to just laugh at the fact he said alcohol or the idea of someone being drunk. You can also see the face visibly lagging behind the head when it moves. The only way I can see this was intentional is if the creator was trying to make a 3D head turn, but none of the parts squished as though they might be cresting over a hemisphere on the head.
I can recommend watching a tutorial by Ross Plaskow on the matter. Just google the name, it comes up quick.
It also got really repetitive about a fourth of the way through too.
