Vile apple pie

Mike was telling Noah about "the Theismann" (Joe Theismann's famous horrible football injury back in the 80's).  He said, "My friends and I made popcorn and watched it over and over." 
Noah said, "You are a vile man, Dad." 
When we laughed, he said, "Was that not the right word?" 
I said, "No, it was apropos." 
He said, "What does apple pie have to do with anything?"
