I got a few:
1 "My so Called Life." In the their Christmas episode it involved a ghost of a teenage girl who had died while being homeless and she was their to help Rickie who was going through a similiar problem.
2 "Family Guy." Stewie has a time travel device and not only that but you got a talking dog and God,Jesus are real for certain.
3"Law and Order." John Munch was in a "X-Files" episode and he went on to be in the "Law and Order" universe. Actually it started even earlier when "Law and Order" did a crossover" episode twice with "Homicide: Life on the Streets."
Also if you want to pick from movies that is okay as well.
