Isn't she saying - went from giving candy to the children (knocking, to trick or treat), to giving them money.
I’m not sure that’s what she’s talking about - I mean, why would she use her boobs to make that point? It makes no sense.
But really she's saying Look at me! I am so youthful! And really edgy! Did I shock you? Talk about me!
Well if that was her objective then she certainly achieved it!
