Don't worry, he remembered once the lyrics "We're breaking free!" came on:
6. Lauren Graham forgot that Lorelai married Christopher on Gilmore Girls. She told Entertainment Weekly the following:
“Christopher [Hayden] and I got married in that season. When we came back to do [the revival], I say something about having been married or somebody says it to me, and I was like, ‘I was never married.’ I forgot," Graham says. "They had to get one of the super-fan assistants to get on the phone with me to remind me. She had to tell me the whole thing. It just seemed so out of character that I literally blocked it from my memory. That was my season 7 experience.”
But, alas, it did happen:
