Meaning of "the butcher, the baker, and the candlestick maker" ?

I heard someone use that line from a t.v show but I do not fully understand what the meaning behind it is. I searched it but all I got was that its from a nursery rhyme. Can someone please tell me the real meaning behind it? Even BETTER if you can use it in a sentence :) Thank you.
