Oliver and his comedy writers went to work, dug deep and found the story of George Moon, who discovered a 12,000-year-old Mammoth fossil in Erie County in the summer of 1991. From there, it wasn't a stretch for them to come up with the new team name.

The SeaWolves had no say on their rebrand name or logo. The Last Week Tonight team dug into Erie’s history to pick Moon Mammoths, a name inspired by the 1991 discovery of woolly mammoth remains in a local lake. Oliver threw out the first pitch at the game, which drew a record-setting crowd of more than 7,000 fans.
