Help me place a movie quote?

There's a quote that popped into my head, and I just can't place it. I'm pretty sure it's a movie quote, and this may not be it exactly, but this is the gist:

"If someone asks you if you've seen a movie you say yes, even if you haven't seen it, because if you say no, you'll have sit through a painstaking summary of a movie that you didn't even want to see in the first place, or worse, a movie you did."

Thanks to anyone who can help me. This is really bugging me! lol
