Nigel Harpington was a former officer on the RMS Titanic and ancestor to Chris' history teacher in "Stewie, Chris & Brian's Excellent Adventure". When the boys find themselves on the Titanic during its sinking, they are denied access to a lifeboat by Nigel. Chris bulls his way onto the boat, shoving Nigel overboard where he drowns. The change in history results in Chris getting a new history teacher who doesn't believe in tests.
