The first episode where Fred the Cockatoo does tricks. It's also the episode where Baretta tells Fred's backstory: When Baretta got off his ship after being in the Navy, Fred, who belonged to the boatswain's mate, flew off the ship to Baretta, and the rest is history.
The second episode of the series and the second time he changes "Italian" to "Itralian" with an R after the T. This turns out to be "one of his things."
