Ooh, I've got another one: I went on a cruise in the Caribbean with a girlfriend, years ago. She and I have been penpals since the year dot - she lives in the UK (Reading, these days) and I live in Kingston (Canada). As we unpacked in our cabin, somehow the talk turned to something health-related - sunburns, maybe? Anyway, my friend said we could always use the Witch Doctor. I was quite bemused but tried to play along, saying, "That's right! Ooo, eee, ooo ah ah, ting tang, wallah wallah bing bang!"

Of course she looked at me very strangely. She'd never heard the song. What she had been talking about was a witch-hazel gel product from the UK, that comes in a tube and is used for stings, rashes, mild burns etc...!

We sang the witch doctor chorus quite a bit over the two-week vacation....
