Finn has a lot of nicknames. Depends on who's talking to him! My older brother has always tried to come up with really random, silly names. He's called him Hyphen (cuz I'd say "Hi, Finn") and Fenny Kravitz, those are the strangest. He also calls him Finster and Finley (from the Dallas Mavericks basketball team). I've always called him some of the more obvious names....like Finnigan and Phinneas. But, Huckleberry and Fenton are my personal favorites. He usually responds to them all, except for Huckleberry. Doesn't sound anything like his name, so, it's like talking to a wall. Ha.
