TC (or Man About The House) has been seen, in one version or another, in dozens of countries. Sometimes the original version has been dubbed, sometimes a new cast was assembled. The title has usually been changed. Here's a list of titles, and I hope my translations aren't too badly off:

UK: Man About the House
US: Three's Company (recast)
Italy: Tre cuori in affitto [Three Hearts In Rent] (TC dubbed, then recast)
Germany: Herzbube mit Zwei Damen [Jack of Hearts with Two Queens] (apparently TC dubbed)
France: Vivre a trois [Living with Three] (apparently TC dubbed)
Poland: Lokatorzy [The tenants] (TC w/Furley, recast)
Russia: Troye Sverkhu [The Three Upstairs] (TC w/Ropers, recast)

Any others?
