Full Moon High (1981)

Teenage Tony goes on vacation with his family to Romania and is bitten by a werewolf.  Once he returns to the US, he starts nipping at women's hinders which naturally freaks people out. Seems better than killing and eating them, but it still causes him to leave town.

Tony wanders around the country and around twenty years later ends up back in his hometown. He hasn't aged a day since high school, so he's mistaken for his own son.  He goes back to school in hopes of winning the championship, which he missed out on as a teen due to that pesky werewolf thing. Not that he's not still a wolf, but somehow it works for him and the kids love him.

This was made before Teen Wolf. Wonder if they got their ideas here since Tony is a werewolf on the football team and also does a werewolf dance. Hmmmm.

This spoof on werewolf movies has jokes that are really dated (they probably weren't even funny in 1982), but it does have some charm. It's not a great movie by any means, but it was kind of fun.
