Party guest (The Lazarus Experiment)
From Tardis Wiki, the free Doctor Who reference
The Party Geust was a female human who lived in London in the 21st century. She attended Richard Lazarus's experiment and joked that the most dangerous thing there was choking on an olive when The Doctor warned everyone to leave. She was then proved wrong when a giant genetic throwback crashed through the door and frightened her away. (DW: The Lazarus Experiment)
