Matt Groening, the creator of The Simpsons is a 33rd degree Mason aka Lucifer worshiper and is known for revealing hidden truths in The Simpsons episodes. This is a clip from a cafeteria in a Simpsons episode where cannibalism is implied.
A different clip from the movie Soylent Green is about "eating people". Sorry if that's too straightforward but this world is messed up. Then there's the awful phone call from a Jewish Rabbi who brags about being a descendant of Cain, making large amounts of "shekels" after abducting, abusing, sacrificing, and grinding up the bodies of children that are sold to their "biggest clients". He specifically mentions McDonald's. Here's that clip:
His comments are so gross and blatant that it makes me question if they are authentic. However, Rabbi Finkelstein has made many other comments that are similarly abhorrent, so it would not be a surprising shock if true.
