Can somebody explain this quote to me
In the episode where the little brother gets his name shaved into his hair, the father is outraged and tries to get the boy's haircut fixed. They end up shaving his whole head and when the older brother sees this he says:
"You look like Charles Barkley, without the mustard."
For years this quote has haunted my mind and damaged my psyche ever so slowly. Can somebody please explain that quote and put my thoughts at ease?
