Joel has decided to have his ex-girlfriend, Clementine, erased from his memory because she had erased him from her memory. At the start of the procedure, the "doctors" put items that remind Joel of Clementine in front of him as they monitor his brain activity. Parts of his brain light up on the machine as he thinks about Clementine. Joel's thoughts are illustrated as incoherent events as the procedure progresses.
Beakman explains that shoes stink because of the bacteria on your feet. He uses a microscope to quickly show that there are bacteria everywhere and then a short animated clip to show how your feet produce oil and sweat that the bacteria eat. This creates smelly biproducts to make your feet stink. He then does a DIY bacteria growth experiment where he grows bacteria from his sweaty feet in a jar of gelatin.
