When you watch Norm Macdonald, and you know about MKUltra, and a general proclivity by a certain tribe to be peddlers of degeneracy, this is one of the creepiest things I've ever seen. The gray man story (at the timestamp: https://youtu.be/BRkueTfH6og?t=4000) is just horrifying.
The one with Craig Ferguson I don't know what to think of. It feels more sad.
