Martin is the school square and is constanmtly getting on Barts nerves by getting the answers to questions correct. He doesn't really have a life and is always a victim of the painful but funny "Wedgy". During one episode Bart had a swimming pool and became very popular Martin realised that if he got a swimming pool he too could become popular. This back-fired in his face and resulted in him having evenm fewer friends. He has also revealed to us his secret den where all his square friends go into when being chased. For those of you people who do not know about it, it is in Martins locker and there is a false back to it.
