On Sunday's episode of Last Week Tonight With John Oliver, John used his homemade Salmon Can**n - yes, Salmon Can**n - to shoot fish at some movie actors, TV stars, and other late-night hosts. He was inspired by a news clip about an actual Salmon Can**n that was created to get fish over dams and help them return to their spawning grounds. After he made his own version of the can**n, John took aim at everyone from Jimmy Fallon to Tom Hanks to Grey's Anatomy's Meredith Grey (Ellen Pompeo), who's busy operating on a patient when she gets slammed in the face by a fish. Also on John's target list? Kelly Ripa, Anderson Cooper, Jon Stewart, and Homer Simpson. Take a look at the fishy situation in the clip above, and then check out more viral videos!
