Mr.Bean is described as "a child in a grown man's body".He is a slow-witted,sometimes ingenious,childishly,selfish and generally likeable buffoon.
Mr.Bean often seems unaware of basic aspects of the way the world works,and he usually attempts to do what would normally be considered simple tasks,such as going swimming,redecorating or taking an exam.The humour largely comes from his original (and often absurd) solutions to any problems and his total disregard for others when solving them,his pettiness,and occasional malevolence.
