Does anyone know where I can watch episodes of Topper online? I know theres some on you tube, but not many and I have seen them.

There are four episodes on www.tv4u.com :

George's Old Flame (they call it "Movie Star")
Second Honeymoon
Las Vegas
House for Sale

Don't know if these are the ones you've seen or not. But "Las Vegas" is a really good one IMO.
