The most disturbing cartoon parent award goes to you guessed it Cow and Chickens mom and dad. I never understood how this happened or why but yea... these two characters are literally just a pair of severed legs. Proof:
  
I am not sure about the second image showing their upper torso. I remember an episode where it showed up and they where just legs also found an image but it was way to large. I have never seen the episode with the upper body's im curious as to what happened to them that made them just legs...

It's Cow & Chicken, a show where a human woman gave birth to both a chicken and a cow. Maybe the shadows were just for fun? Cartoons back then made no sense at all at times. Like how Dexter had a whole laboratory behind a bookcase in his room and his parents didn't notice.

I am not bashing the show in any way I was just always curious as to why they where legs... Other then that great show.
I guess the mystery stays unsolved.

well think about this i have seen this happin not in cow and chicken but in tom a jerry if anyone has seen the orignal one but still who know what with them
