Mike Hamar (Wayne Robson) is a career criminal who was taken into Possum Lodge by Red Green for rehabilitation. While a nice guy in general, Mike's sticky fingers are always getting him into trouble, as he is constantly being found with other people's wallets, keys and possessions. He knows a lot about the criminal justice system, including what it's like to be in jail and how to ward off other criminals. This knowledge, ironically, lands him a job as a police officer at the end of the series, as well as getting him a brief (and unsuccessful) stint as a policeman in Mike Goes Straight.
In his earliest episodes, Mike wore a short pigtail and showed a strong inferiority complex, calling himself "useless" and apologizing for making simple mistakes, particularly in handyman projects. Over time, however, he dropped the pigtail and became more cheerful, open and outgoing.
Periodically, other Lodge members would embarrass Mike by bringing up his criminal past out of the blue, usually by saying that people should stop bringing it up all the time.
In Father and Son Banquet, Mike says that his mother is Bambi Bazooms the Feather Dancer.
