I am glad that a few people said they enjoyed it. Others such as yourself may not like this type of humor. It does not take much analysis.
My wife and I were watching the entire video and then this clip came along and we were caught off guard, but it made us laugh our butts off. We watched it a couple more times mostly because it was so funny but it also made us realize that the speed of movement, the body and the surroundings were not right.
I thought it was very funny, watched it several times in fact, and was indicating that indeed it is not meant to be anything other than a joke as you correctly surmised. 🙂
