When Pi was twelve years old his Roman soldier stood in the schoolyard, pointing at him and yelled "It's Pissing Patel!" Many of his classmates would say "where's Pissing? I've got to go"  others would say "You're facing the wall. Are you Pissing?" He later attended St. Joseph's, his first day of class Pi went to the board and clearly wrote out "My name is Piscine Molitor Patel, known to all as pi Patel, 3.14" Since that day nobody called him "Pissing" now he was known to all as "Pi"
