On yesterday's episode of Last Week, Tonight, John Oliver sat down with the world's foremost chimpanzee expert and general badass Dame Jane Goodall, PhD, as part of his Great Minds: People Who Think Good series.

Oliver bravely asked the super charming Goodall some of society's more burning questions like, why chimps make bad pets and if she had really never thought to put a chimp in a butler outfit with a monocle. They then collaborated on the greatest name for a chimp ever—"Poo-throw Hitler" and ate a banana together.

Oliver also gave a solid rant about candy, sugar content, and the various corporations trying to downplay health risks of sugar.
