Thanks Neo!
In my opinion, putting mouthwash/toothpaste/soap/shampoo/deodorant on your Christmas wish list isn't such a bad idea : if you have any pranksters in your family, they will be thrilled to give you a present that implies that you smell bad without you being offended!
(Giving someone one of those items as a present is usually a way to tell them that you think they smell bad.)
