Well, in this country, the thing was first published as the Kokey-Cokey; the name was later changed to the familiar "Hokey-Cokey" soon afterwards, probably in the interests of common sense (relatively speaking).

Hokey-pokey is ice-cream, as sold by Italian immigrants (Hoco uno poco - take a piece).

Sorry, is this a bit serious? If you prefer your party entertainment sitting down, you can't beat the great game of name ten famous Belgians. I found out on Sundaty that Georges Simenon (authour of the Maigret stories) was Belgian. That should start you off.
