The short film includes a brand new song entitled "The Brain Song," in which the last few minute of the short are of the music video. It starts with a picture of the brain which then starts to move. It shows you that he brain is "divided into two hemispheres" and that the left side "controls your right side and your left controls your right side" which happen to be "tied together" by the Corpus Callosum, as well showing that the brain is covered with a meninges layer, cerebral spinal fluid and afterwards you are looking at the four lobes of the brain, which compose of the Frontal, the temporal, the parietal and the occipital lobes and that they are all important. It shows you that the reason we can see things is because "eyes cones are sending stimuli to your thalamus, which joins up to your occipital lobe," and that you can hear things when the "scilia down in your ear" vibrate and send "those impulses along to your temporal lobe." Al then shows through a telescope how the different parts of the brain can "communicate with each other." It shows a school of neuron, "a funky funky neuron," which has an axxon on one side and a denox on the other side. It then shows what happens when a neuron's denox gets a signal from another neuron, it "sparks a chemical reaction in the nucleus," which creates a "nerve impulse which travels down a long long myelin coated strand." The neurotransmitter molecules then enter the vesicle of the axon terminal, and then the neurotransmitters "jump a millionth of an inch across the synaptic gap" which then enter into "the receptors of the dendrox of another neuron," which connects "neuron to neuron to neuron to neuron all across your entire brain." This also explains that the more you use your brain, the smarter you'll be. The film ends with Yankovic saying to "[always] wear a helmet".[3]

The short film was released to the public at the Orange County Fair 2009 airing from July 16 to August 15.

The short has yet to be released on home media. However, its original song, "The Brain Song" was released on the Medium Rarities album, exclusive to the 2017 box set Squeeze Box.
