Now that Barb's finished the last Harry Potter, she Kim and I were sitting around talking about who would be the next head of school. I said, "Maybe it'll be Slugworth, er, Slughorn." Kim laughed, remembering her Charlie and the Chocolate Factory.
I went on, "Yeah, and at the end he'll give Harry an everlasting gobstopper."
After a second, Barb said, "Did you just make something dirty up?" I said no, but then thought again. A quick google found this entry, of course.
