Animaniacs
Space Probed / Battle for the Planet
S1 E15:
When aliens abduct the Warners as they vacation at a remote cabin, the wacky siblings are "Space Probed." Then, inspired by Orson Welles' famous 1938 radio broadcast of H.G. Wells' "War of the Worlds," Pinky and The Brain stage a fake alien invasion in "Battle for the Planet."
