Yes, they certainly do! *shudder*
LOL! Now I'm going to have to go and re-read it!
Hopefully, my UK copy of the book will have arrived by now and I'll be able to re-read with a clear conscience. I'd bought a US copy of the book for my nephew's 7th birthday, and I read his the instant it arrived. But, as I've said, I cannot risk reading his copy again.
