Tom Thumb
From Tardis Wiki, the free Doctor Who reference
Tom Thumb was the smallest elephant in P T Barnum's circus.
On 15 September 1885, in St Thomas, after performing, Tom Thumb was being transported along across track with Jumbo the Elephant. A train travelling along the track hit Tom Thumb throwing him off the track. The train then hit Jumbo, killing him.
The Fourth Doctor and Sarah Jane Smith watched this event with the TARDIS scanner. (AUDIO: The Wondrous Box)
