Hamburgurlar Is Back

McDonald's just announced that the Hamburgurlar is coming back.  Back from the dead?  The original Hamburgurlar had to have died by congestive heart failure or stroke.  Just like Popeye's pal Wimpy.  

On this McDonald's mascot note, what the hell was Grimace supposed to be?  I know his name derives from the face you make five minutes after finishing your meal, but what was he?  I am pretty sure Gimaces' love child went to college with me.  I had a class with a girl that looked just like him minus being purple.
