"My inn's as clean as..."

My internet connection has been spotty lately, but at least I was able to download Baldur's Gate for my iPad. I've started up a new game with an archer ranger, and my five-year-old is trying out a shapeshifter druid. After spending some time in Candlekeep, he picked up the catchphrase of the local innkeeper: "My inn's as clean as an elven arse!" Now he's saying it non-stop. Amy is not as amused as I am...
