Sam

Sam-san (サムさん, full title: "Ordinary everyday person" Sam-san) is a random drunk that appears in One Piece on very rare occasions. The idea behind him is the same as Pandaman, only he is much rarer to see and normally less noticed. His first appearance was during the Arlong arc when everyone was celebrating Arlong's defeat. His story according to Oda was he was on his way home from his daughter's wedding, drunk, saw a party and decided to join in. He is also seen in the Loguetown arc as one of the judges of the cooking contest.

He is next seen in the Arabasta arc in the manga. Oda went on to explain he was there because his second daughter was getting married. He also said his wife had left him when their eldest was 8 and he ended up raising all his daughters on his own. The second daughter was apparently the trouble maker and despite the trouble she gave him, when she got married he went out and got drunk because it saddened him that she was leaving. Somehow he ended up in Arabasta after having one too many drinks.

Sam is one of Oda's jokes in the SBS corner, although it was more likely just a less-than-serious answer Oda came up with to answer the question as to why the same random drunk was in two different panels in the manga. Sam-san has made few appearances in the Manga, however he has been featured in the background of the One Piece anime on several occasions.
