where does Muscle Man get his name when he is the complete opposite of ripped

Actually I think Muscle Man's name is based off of Sarcasm,because his name indicates the opposite of what he actually is..

Probably because the does active things for his job (like in the Starla episode), even though he's out of shape.

I think the creator likes sarcasm... muscle man is obese>:)

i think he just likes to call himself that either because
1). he isn't smart and he thinks he's muscular but really he's fat
2). he didn't like the name Mitch.
或者 3). both of the reasons
