Bigfoot
From Tardis Wiki, the free Doctor Who reference
Bigfoot was a creature famous for being caught on the Patterson-Gimlin Bigfoot film. Her real name was Geraldine and she told River Song she was upset that she was filmed on a bad hair day. (PROSE: Suspicious Minds)
An episode of The World's Strangest Mysteries covered a Bigfoot sighting. Jenni Marcel would later remark that it was "obviously a man in a gorilla suit". (AUDIO: Kronos Vad's History of Earth Vol. 36,379)
