Mr. Pignati is an older gentleman who lives alone on Howard Avenue. His wife died awhile back, but he tells people that she is on vacation in California. He has a fun and interesting personality and he doesn't mind smiling a lot. He is also generous because when two teenagers, John and Lorraine, ask him for ten dollars for a fake charity, he willingly gives it to them. He invites the teenagers to get to know him better by joining him at his favorite place--the zoo. He introduces them to his best friend, Bobo, a baboon. Mr. Pignati is also generous because he buys the kids skates and then allows them to skate around in his house. He also winds up being like a father to Lorraine because he even buys her nylons that she needs, which she appreciates greatly. Mr. Pignati is so kind and generous that he fills a void in the tennagers' lives since both have issues at home with their own parents. In the end, he dies of a heart attack, but the kids are so grateful to him that they write a memorial book in his honor called The Pigman.
