Last Week Tonight with John Oliver went out with bang in its season finale. The host built his own version of a salmon cannon, which helps the fish get past dams so that they can spawn upriver. This cannon fired fish at various celebrities starting with his old boss Jon Stewart in the middle of filming the Daily Show. Oliver schooled other celebs including Anderson Cooper, Stephen Colbert, Jimmy Fallon, Seth Meyers, Kelly Ripa, Tom Hanks, David Letterman, Joel McHale, Jesse Tyler Ferguson and Eric Stonestreet and J.J. Abrams on the set of Star Wars 7 with R2-D2. There was even original animation from The Simpsons featuring Homer Simpson being buried in a pile of fish but he didn’t seem to mind. Now if only there was a Last Week Tonight cannon to speed up season 2.
