We meet a writer (Rafe Spall) chatting with Adult Pi (Irrfan Khan). He is beginning his story, but first, he starts with the origin of his name. His "honorary" uncle (whom he calls "mama-ji") was a frequent swimmer thanks to his large chest and skinny legs. He went to a pool in Paris that was "so clear, you could make your coffee there." The pool was called Piscine Molitor, and therefore, Pi's full name was Piscine Molitor Patel. However, as a child, other people had a hard time pronouncing it, and the kids would taunt him by pronouncing it "Pissing." Having had enough, he abbreviates his name to Pi, and is shown in math class having full knowledge of the entire equation for pi.
