First thanksgiving with my wife's family. She had an uncle who is diabetic. All the pies had whole wheat crust and were sugar free. As was the cream. Ick.
I was with my extended family having a HUGE thanksgiving dinner once. I had a piece of pumpkin pie, but there hadn't been any whipping cream when they were handing out the pies. So a minute later my crazy uncle comes by with a big bowl of whipping cream and asking who needs some. Yeah - I had a brain fart and forgot who I was talking to and told him I needed some. Took a bite - and it was N A S T Y. Super nasty. Quickly learned it was cream from his goats, and he hadn't bothered to put any vanilla or sugar in it.
Now - any time thanksgiving dinner is with anyone I'm uncertain about, my wife knows that we need to have pie at home...just in case.
