I used to have pet ducks, and they are pretty cool pets. I had one that followed me around, it was a group of 11 ducklings that were born here and he was kinda like the runt, so he bonded with me more than the rest. I really like ducks as pets, more than chickens or geese. I don't know if you can potty train them, but I think that you can't potty train birds at all, might be wrong, though... someone with more knowledge about birds should answer that one. Mine lived in the backyard, so it didn't matter anyway.
