Jonah (mythology)
From Tardis Wiki, the free Doctor Who reference
Jonah was a figure in Earth history who encountered misfortune at sea, (AUDIO: Jonah) and survived being caught inside a whale. Though Peri Brown believed Jonah was merely a myth, the Sixth Doctor claimed to have met the man, describing him as a "nice chap". According to the Doctor, Jonah became a vegan, and would "go mad" at the mere sight of seafood. (AUDIO: The Song of Megaptera)
After Bliss mentioned not wanting to be the "next Jonah", the crew of the Bloodhound began calling their captain, the Eighth Doctor, "Captain Jonah". The name stuck, and the Doctor grew fond of it. (AUDIO: Jonah)
