Watch John Oliver Shoot Salmon Out Of A Cannon At Celebrities


John Oliver closed out "Last Week Tonight" with a bang on Sunday -- literally -- by creating his very own "Salmon Cannon" that launches fish at pretty much any celebrity he wants.

The Salmon Cannon, which Oliver first saw on a CBS News segment, is a vacuum contraption used to shoot salmon over dams to help the fish make it safely to the other side.

"Sometimes people say the news has lost its touch," he said. "But every now and then, they fucking nail it."

Oliver wanted to try out this new incredible invention, so he made one of his own, and began firing fish at television stars and news anchors like Anderson Cooper, Jon Stewart, Meredith Vieira and Jimmy Fallon. Even Homer Simpson got a taste of the Salmon Cannon.
