Although seemingly elderly, Hans Moleman once claimed that he was only 31 years old, implying in the process that his appearance is due to heavy drinking and not a result of old age. However, his age would later be contradicted due to continuity errors. He served at least 4 terms as Mayor of Springfield, during which he balanced the town's budget eight times and claimed to have written the town anthem (although he actually bought the song). He was in his 4th term in office 30 years ago, which contradicts his claim of being only 31 years old in the present day.
He has cataracts and is almost entirely blind, which has severely impaired his reading ability. He carries a brown cane with him everywhere, which was once shown to contain a hidden sword. He is also known to be a war veteran.
Hans was once mistaken for Bart and accidentally "de-programmed" (Homer and Marge had hired a cult de-programmer, hoping to convince Bart to move out of Mr. Burns' mansion and back in with them), apparently leading him to believe he is the son of Homer and Marge. At one time, it was revealed that Hans Moleman slept with Lars Ulrich's grandmother, and is considered by Metallica to be a "real fan".
Homer once stumbled across Hans Moleman as the leader of a race of Mole People in an underground fortress complete with earthquake machines.] In the opening credits for The Simpsons, Marge strikes Moleman with her car. He has some jobs such as a mail man and a janitor (in the episode where Homer gets good luck).
His home address was 920 Oak Grove, Springfield.
Apparently, he had a father who lived at Springfield Retirement Castle.
Hans Moleman once attended Springfield University for a short time, only so that he could have somewhere to sit. One of the college girls refers to him as an "80 year old man" only referring to his old appearance. It is unknown how long he attended the school and whether he gained any credits.
