On Jimmy Kimmel Live last night, Zooey Deschanel shared the story of how her older sister Emily used to torment her growing up by pretending she was an alien. Zooey explained, "She basically just used the plot of Invasion of the Body Snatchers to terrify me." With her morbid imagination it's no surprise that big sis Emily grew up to become a forensic anthropologist on the crime drama Bones. Watch Zooey tell the too-funny story now of the long-running extraterrestrial ruse that Emily would act out during their childhood. If you have a sister, did you have any similar stories from your childhood?
