Captain Hero and Super-Dagwood
When I was a kid I wondered why characters like Jughead Jones or Dagwood Bumstead were depicted so lean and lanky despite how often they were shown chowing down on burgers or giant sandwiches.  The answer was clear of course - they burned off all of those extra calories by fighting crime as costumed vigilantes in their spare time!  It all makes sense now.
