I just remembered at the end of the song, Spangler says you can even eat the dishes. What does that mean?
Discussion
The song was originally in Willy Wonka. That is why the implication of the candy man being a drug dealer doesn't fit the lyrics perfectly.
I still think they meant it as a drug dealer implication in Malcolm in the Middle. Francis explicitly says "Isn't he a convicted felon?" Spangler replies "he was acquired" and another student interjects "so was I but I'm still here"
