A Mooseman is a hypothetical cross between a man and a Moose. This was suggested by Brian when the family were discussing Howie finding out about Brian and Sophie being aliens. When Mel mentioned Brian growing moose antlers he argued that it didn't have to mean he is an alien, saying it could mean he is a mooseman. Shortly after, when Howie witnessed Brian growing moose antlers after eating ice cream, he told him he was a mooseman, causing him to run away in fear. (Howie)
