Sadly, this almost happened to me once. I was a funeral for my husband's grandmother and all of a sudden the preacher started talking about aliens. And he was really going off about how aliens couldn't possibly exist because the Bible doesn't mention them. My husband was a pallbearer so he was sitting in the front several pews away from me, but he turned around and gave me the strangest look. I had to stifle a laugh and pretend it was a sob. Literally nobody else at the funeral even noticed the lengthy alien speech. I guess they were grieving too much. My husband asked some of them about it later and they all thought he was crazy, but I heard everything too and could confirm his story.
