You’re probably already thinking about your Memorial Day plans, but you need to focus your attention on the video below before attempting to engage in any sort of social gathering this weekend. The Science Channel has released a promotional clip for the fifth season of Through the Wormhole, which features Morgan Freeman delivering his narration after inhaling helium from a balloon. He’s discussing unusual situations in science, but there’s really no reason for the Oscar-winner to give us a taste of his chipmunk voice, other than the fact that Jimmy Fallon’s love of making celebrities do weird stuff is infiltrating society. Enjoy.
