The best Halloween candy ever? Boo Peeps! They just might be the best candy ever, regardless of holiday. Not just for taste (though sugar coated marshmallows are quite delicious), but for cuteness and overall eating entertainment.
The worst candy ever? The life-sized gummy severed foot I saw at wal-mart. I can't find it anywhere on the internet, or I'd post a picture. Maybe that's for the best. It was quite disgusting.
